United States

US settlement & citizenship

The US settlement and citizenship category covers the longer-term outcomes of the immigration system — becoming a lawful permanent resident (a Green Card holder) and, later, naturalizing as a US citizen. Green Cards are obtained through employment, close family, humanitarian programs, or the Diversity Visa lottery; people already in the US in an eligible status may apply to adjust status (Form I-485), while those abroad use consular immigrant-visa processing. Most permanent residents can apply to naturalize (Form N-400) after five years — or three years if married to a US citizen — subject to residence, physical-presence and other requirements. This section groups these routes and links to the official USCIS and U.S. Department of State guidance so you can confirm what applies to you.
