What HR Should Clarify Before Giving Anyone a Timeline on a U.S. Transfer

Leadership has asked when the employee can start work in the U.S. The employee, meanwhile, is asking when they can give notice on their flat. You’re finding yourself in the untenable position of being pressured to confirm something without yet having the information needed to do so.

Your instinct to wait before committing is the correct one. The honest answer to a U.S. transfer question is rarely a single day on the calendar, or a single number, but the result of a complex set of variables.

The purpose of the following article is to set out those variables that determine whether any U.S. visa timeline is realistic, giving you the language to clarify each before you commit to promising a date.

At a glance: Before HR confirms a U.S. transfer date, eight variables need to be clarified: the visa category, the employee’s location, whether premium processing is available, the relevant consular post, the H-1B fiscal year cycle if H-1B applies, whether an LCA is required, the company’s document-readiness, and any case-specific complications. Average processing times do not answer the timeline question. These variables do.

Why “How long will it take?” is the wrong first question

• Most U.S. visa timelines published online are average processing times. Average is not the same as predictable. Two L-1 cases filed on the same day, by the same UK employer, can take three weeks apart at the consular stage and three months apart at the USCIS stage.
• The average is also rarely the relevant number. The relevant number is whether your specific case can be processed in time for your specific start date, and that depends on the eight variables in this article, not on a published average.
• Committing to a date based on an average puts the HR contact in the position of explaining a delay later. Committing to a date based on the variables (“the start date is realistic if the consulate appointment falls within four weeks; we will have a clearer picture in the next ten days”) is much more defensible.
• In 2026, the gap between expected timelines and actual timelines has widened. The September 2025 Presidential Proclamation introduced a $100,000 supplemental fee on most new H-1B petitions for beneficiaries outside the United States, with implementation guidance still being clarified and federal litigation pending. Consular appointment availability has tightened in several London-area posts. Premium processing fees increased on 1 March 2026. These are the kinds of variables HR contacts can no longer assume away.

The eight variables that determine any U.S. visa transfer timeline

1. Which visa category applies

The first and most important variable is the visa category itself. Different categories have fundamentally different timelines, because they are processed through different procedural pathways.

• An L-1 intracompany transferee is filed with U.S. Citizenship and Immigration Services (USCIS) on Form I-129 by the U.S. entity. It can be accelerated using premium processing.
• A cap-subject H-1B specialty occupation petition for a worker who has not previously been counted against the cap is tied to the annual H-1B cycle, with electronic registration in March and the earliest employment start date generally falling on 1 October.
• An E-2 treaty investor visa for an investor, executive, supervisory employee, or essential-skills employee, depending on the facts and treaty-company nationality, is processed at a U.S. consulate (in London for UK nationals; through the U.S. Embassy for Irish nationals applying from Ireland) without a USCIS petition stage.
• An O-1 extraordinary ability visa is filed with USCIS on Form I-129 and is eligible for premium processing.

Why this matters: Until the visa category is identified, no timeline is meaningful. “How long does it take?” is impossible to answer until the answer to “which visa?” is settled.

What HR can clarify: Whether the lawyer has confirmed the visa category in writing, and whether more than one category may apply. If more than one applies, the timeline question changes shape entirely.

2. Whether the employee is inside or outside the United States

Where the employee is physically located when the petition is filed, and when it is approved, significantly changes the timeline.

• If the employee is already in the U.S. in another valid status (for example, on an existing visa), a change of status can sometimes be requested as part of the same petition. They do not need to leave the country and return.
• If the employee is in the UK or Ireland, USCIS approval (where required) is followed by a separate consular stage at a U.S. embassy or consulate. That stage can add days, weeks, or longer depending on the visa category, the post, appointment availability, document review, passport return, and any administrative processing.
• This variable also changes whether the September 2025 H-1B supplemental fee applies. As of current USCIS implementation guidance, the $100,000 supplemental fee applies primarily to new H-1B petitions for beneficiaries outside the United States. Petitions for change of status, amendment, or extension for beneficiaries already in valid status in the U.S. are generally not subject to the fee, although exceptions exist where USCIS finds the beneficiary ineligible for in-country adjudication. The implementation rules continue to be litigated and refined; specialist advice is essential.

Why this matters: Two employees with identical facts can have meaningfully different timelines and meaningfully different costs depending solely on where they are located when the petition is filed. This is one of the most under-discussed variables in HR planning.

What HR can clarify: Where the employee is physically located right now, what their current immigration status is in the country they are in, and whether there is any flexibility on those points before the petition is filed.

3. Whether premium processing applies, and what it does not solve

Premium processing is a USCIS service that requires USCIS to take adjudicative action within 15 business days after USCIS properly receives Form I-907, the correct fee, and the underlying eligible filing.

As of 1 March 2026, the premium processing fee for L-1, H-1B, and O-1 petitions filed on Form I-129 is $2,965 (previously $2,805).

Premium processing is genuinely useful, but it is one of the most over-relied-on parts of the timeline picture. HR contacts often hear “premium processing” and assume it solves the speed problem. It only solves part of it.

• What premium processing does: It guarantees that USCIS takes some action (approval, denial, request for evidence (RFE), or notice of intent to deny (NOID)) within fifteen business days of filing.
• What premium processing does not do: It does not improve the chance of approval. It does not speed up the consular stage if the employee is outside the U.S. It does not speed up Labor Condition Application processing for H-1B cases. It does not bypass the H-1B annual cap. And if USCIS issues an RFE rather than an approval, the fifteen-business-day clock pauses until the response is filed and processed, which can add weeks or months.

Why this matters: An HR contact who tells leadership “we’ll just pay for premium processing” without understanding what it actually accelerates is going to disappoint someone.

What HR can clarify: Whether premium processing is available for the chosen visa category (it is not available for every category), whether the lawyer recommends using it for this specific case, and what stages of the process premium processing does not affect.

4. The current consular wait time at the relevant U.S. embassy or consulate

For employees outside the U.S., the consular stage is often the most variable part of the timeline, and the part most outside any lawyer’s or HR contact’s control.

• UK nationals applying for an L-1 or H-1B visa apply at the U.S. Embassy in London. Wait times for nonimmigrant visa appointments fluctuate. Specialist E-2 visa applications for UK nationals are processed by the London consulate’s specialist E-visa unit, with a published 90-working-day processing period, roughly four to five months from filing.
• Irish nationals apply at the U.S. Embassy in Dublin. Wait times and processing approaches differ from London.
• Some applicants from third countries, for example, an Indian-national employee being transferred from a UK office to a U.S. office, may face additional considerations regarding where they can apply, as U.S. consular posts have been more strictly enforcing rules in 2025-2026 about visa applications taking place in the country of nationality or legal residence.

Why this matters: A perfectly prepared petition that receives USCIS approval in fifteen business days can still take months to result in a visa stamp if the consular wait at the relevant post is long. The consular variable is what most HR contacts forget.

What HR can clarify: Which embassy or consulate the employee will use, what the current published wait times are at that post, and whether the lawyer is monitoring those wait times for this specific case.

5. The H-1B fiscal year cycle, if H-1B applies

If the chosen category is H-1B and the employee is not already a current H-1B holder, the timeline is fundamentally constrained by an annual statutory cycle that does not move.

• USCIS holds an annual electronic registration period in March. Selected registrations are then permitted to file H-1B cap-subject petitions during the April–June window for the federal fiscal year that begins on 1 October.
• The annual cap is 85,000 visas (65,000 in the standard category and 20,000 reserved for beneficiaries with U.S. master’s degrees or higher). For FY 2027, USCIS completed the initial H-1B registration selection process in March 2026. Only selected registrants are permitted to file cap-subject H-1B petitions during the filing window.
• If a registration is not selected, the employer cannot file a cap-subject H-1B petition for that fiscal year. The next opportunity is the following March.
• Cap-exempt H-1B petitions for certain higher education, non-profit research, and government research employers are not subject to this annual cycle and can be filed year-round. Most UK and Irish corporate employers are not cap-exempt.
• Since 21 September 2025, certain new H-1B petitions for beneficiaries outside the United States may require a $100,000 payment under the Presidential Proclamation. USCIS guidance has treated some in-country change-of-status, amendment, and extension petitions differently, but the analysis is case-specific and continues to be affected by agency guidance and litigation.
• From the FY 2027 cycle onward, USCIS no longer runs a purely random lottery against the H-1B cap. Under a final rule effective 27 February 2026, the selection process is weighted toward higher prevailing wage levels. Registrations filed at Level IV receive the most entries in the selection; registrations filed at Level I receive the fewest. This changes the strategic conversation about H-1B sponsorship: the wage at which the role is registered now affects selection probability, not only compliance, once selected.

Why this matters: An HR contact who is told the employee “will need an H-1B” without being told what the H-1B cycle currently looks like is being given dangerously incomplete information.

What HR can clarify: Whether H-1B is the right route given the cycle position, whether the employee has ever been counted against the cap before (which can change the analysis significantly), and what the alternative routes are if the H-1B cycle does not align with the start date.

6. Whether a Labor Condition Application is required, and what it adds

For H-1B, H-1B1, and E-3 cases, a Labor Condition Application must be certified by the U.S. Department of Labor. For H-1B, the certified LCA must be in place before the Form I-129 petition is filed with USCIS. For H-1B1 and E-3 cases, the certified LCA is required for the visa application or for any USCIS change or extension filing.

• The Department of Labor processes electronic LCA filings within seven working days from receipt.
• The LCA cannot be filed more than six months before the intended employment start date.
• The LCA requires the employer to attest that it will pay the required wage, generally the higher of the actual wage paid to similarly employed workers or the prevailing wage for the role and work location, and comply with required working-condition attestations. A new rulemaking initiated under the September 2025 Presidential Proclamation is expected to revise prevailing wage levels; HR should treat current wage requirements as subject to change.
• L-1, E-2, and O-1 petitions do not require an LCA. This is one reason these categories are sometimes faster than H-1B for cases that qualify for them.

Why this matters: The LCA stage is invisible to most HR contacts, but it is real, sequential, and on the critical path for any H-1B-based timeline.

What HR can clarify: Whether the chosen category requires an LCA, and if so, what wage level applies and whether the company’s intended salary meets it. Salary mismatches at the LCA stage are a common cause of avoidable delay.

7. The company’s document-readiness on the corporate side

Most timeline conversations focus on what USCIS, the Department of State, or the Department of Labor will do. Few of them focus on what the company itself has to produce and how long that takes.

For a UK or Irish employer transferring an employee to the U.S., a complete petition typically requires:

• Evidence of the qualifying corporate relationship between the UK (or Irish) entity and the U.S. entity: articles of incorporation, share registers, organisational charts, intercompany agreements.
• Financial documentation for both entities: recent accounts, tax filings, evidence of active business operations.
• Detailed job descriptions for both the employee’s qualifying role abroad and the proposed U.S. role, drafted to the legal standard required by the visa category (executive/managerial for L-1A, specialised knowledge for L-1B, specialty occupation for H-1B).
• Proof of the employee’s continuous qualifying employment abroad. For L-1, this means at least one continuous year of qualifying employment with the corporate group abroad within the three years immediately preceding the petition.
• The employee’s qualifications, including academic transcripts and professional credentials, often verified through formal evaluation.

Producing this documentation to the legal standard required is rarely a quick task. It typically takes a UK or Irish HR team two to four weeks to assemble a complete petition package, even with a structured intake process. For first-time petitioners, it can take longer.

Why this matters: The official processing times start when the petition is filed. They do not include the time it takes to prepare the petition. HR contacts who do not factor this in find that their case has been “sitting with the lawyer” for three weeks before any government clock has even started.

What HR can clarify: How long the lawyer estimates the document preparation stage will take, and what specifically the company needs to provide. The earlier this list arrives, the less of it ends up on the critical path.

8. Whether the case is straightforward or whether complications are likely

The final variable is the one most often underestimated. Some cases are straightforward. Some cases have features that materially increase the timeline, and they are not always obvious from the outside.

Common complications that lengthen U.S. visa timelines for UK and Irish employers include:

• In premium processing, an RFE or NOID stops the premium processing clock, and a new premium processing period begins after USCIS receives the response. In regular processing, an RFE can add weeks or months because the employer must prepare the response and USCIS must resume review. L-1B specialised knowledge cases historically draw RFEs more often than L-1A executive/managerial cases.
• A new office L-1 petition, where the U.S. entity has been operating for less than one year, receives more detailed scrutiny than petitions for established U.S. operations.
• Prior U.S. immigration history that needs to be addressed, including any previous visa refusals, prior U.S. entries, or any past U.S. immigration violations. These do not automatically disqualify a case but they change the picture, and the lawyer needs to know about them up front.
• Complex corporate ownership structures, particularly for businesses recently acquired by a private equity or holding company, can require additional evidence to establish the qualifying corporate relationship.
• Third-country nationals being transferred from the UK or Irish office, for example, an Indian-national employee on a UK skilled worker visa being moved to the U.S., may face consular processing requirements that differ from those for UK or Irish nationals. Current Department of State guidance directs nonimmigrant visa applicants to schedule interviews in their country of nationality or residence, with limited exceptions.

Why this matters: An HR contact who is given an average timeline without being told whether their specific case has any of these complications is being given a number that may not apply to them.

What HR can clarify: Whether the lawyer has identified any case-specific risk factors, and if so, how those factors should be reflected in the timeline given to leadership.

How to use this framework before promising a date

• Before committing to a date, ask the lawyer to walk through each of the eight variables for the specific case. The answer should not be a single number; it should be a range, with the variables that drive each end of the range identified.
• Translate that range for leadership. “The earliest realistic start date is X, assuming the consulate appointment is available within four weeks and no RFE is issued. The latest realistic start date is Y, if either of those assumptions slips. We will have firmer numbers in the next ten days, after the petition is drafted and the consular appointment is requested.” That kind of language protects the HR contact, the leadership team, and the employee.
• Avoid promising a specific date until at least the first three variables (visa category, employee location, consular post) are clarified in writing. These three variables alone determine the basic shape of the timeline. The other five refine it.
• If leadership presses for a specific date before these variables are clarified, the most useful response is not to negotiate a date, it is to explain which variables are still being clarified and when they will be confirmed. This is calmer for everyone than a date that is later revised.
• Keep the employee informed in the same language. The employee is making personal decisions (notice on a flat, schools for children, a partner’s job) based on the date they are given. Honest variables are kinder than optimistic dates.

What a realistic timeline conversation looks like in practice

• A useful first conversation about timeline should not produce a single date. It should produce a structured assessment: which visa category applies, where the employee is currently located, what the current consular wait looks like at the relevant post, whether premium processing helps, and what document preparation will require.
• At Flynn Hodkinson, the initial consultation is structured around the facts of the case. Janice will identify which of the eight variables apply, which create critical-path risk, and what the realistic earliest and latest start dates are based on those variables. That framework is the deliverable, not a guarantee.
• Sometimes the honest answer is that the start date leadership has in mind is not achievable on the route initially proposed, but is achievable on a different route. Sometimes the honest answer is that no route delivers the start date and a different conversation is needed with leadership and the employee. A good first conversation surfaces these distinctions clearly.
• The lawyers at Flynn Hodkinson are regulated by their U.S. state bars and provide specific legal advice, not general guidance. The final decision on whether a U.S. visa is issued rests solely with the relevant U.S. government agency, but the realistic timeline for getting to that decision can be assessed honestly with the right facts in front of you.
• What you leave the consultation with: a written assessment of the variables, a defined range for the realistic timeline, an honest view of where the risks sit, and the language you need to brief your leadership confidently.

A note for HR contacts managing their first U.S. transfer

• If you are managing a U.S. visa transfer for the first time, the timeline question is the part that feels most exposed. You are being asked for a number you do not yet have the information to give, and the people asking (leadership, the employee) do not always understand why you cannot just give one.
• That is not a failure of preparation. It is a feature of the process. U.S. immigration timelines depend on more variables than any HR contact can be expected to track in real time.
• The most useful thing a first-time HR contact can do is name the variables before being asked for the date. “The timeline depends on the visa category, the consular wait time, and how quickly we can prepare the petition. I will have a clearer picture in the next ten days.” That sentence, said before leadership asks, changes the conversation completely.
• If you find yourself in a position where you have already given a date and now have reason to think it is unrealistic, speak to the lawyer immediately. Revising a timeline early, with a clear explanation of which variables shifted, is far less damaging than missing it later.
• Many HR contacts find that the first U.S. transfer is also where they learn the most about the process. The variables in this article do not change. The next case will be easier, particularly if you build the right relationship with a lawyer who knows your company. That relationship is what most experienced Global Mobility Managers describe as the difference between handling U.S. transfers reactively and handling them well.

What to do next

A realistic U.S. visa transfer timeline is not a single number. It is a function of eight variables: the visa category, the employee’s location, premium processing, consular wait times, the H-1B fiscal year cycle, the LCA, document readiness, and case-specific complications. The HR contact’s job is not to know each of these variables in detail. It is to make sure each of them has been clarified in writing before a date is given to leadership or the employee. Done well, that approach can substitute a defensible plan for an anxious promise.
