US Green Card Services and Support with Permanent Residency Applications
The most common US immigrant visa types that allow individuals to immigrate permanently to the US are employment, investment and family-based visa categories.
In most cases, to immigrate permanently to the US a person will need to be sponsored by an an American employer or an immediate family member who is a US citizen or lawful permanent resident. There are also some categories that allow a person to apply without a sponsor if they have extraordinary ability in a specific field, or if the person is working in an area that is in the American national interest.
Other immigrant visa options are available for asylees, refugees and winners of the Diversity Visa Lottery.
