You can apply for permanent resident status after 3 years of living in the U.S. in U nonimmigrant status.
Note: When you apply for permanent resident status, you can apply to get your work permit at the same time based on your application for permanent resident status. That way you can get a new work permit while USCIS is processing your permanent resident status application. It is possible you might get the work permit before the U visa work permit expires, but you might not. But, if immigration gets your application for permanent resident status before your U nonimmigrant status expires, your U nonimmigrant status is automatically extended while your application for permanent resident status is pending. Your permission to work is also automatically extended.
Remember: Look at your I-94 card to find out when your status started. If you got U nonimmigrant status while in the U.S., your I-94 card is at the bottom of your approval letter from USCIS. If you came into the U.S. on a U visa, you need to print your I-94 card from the website www.cbp.gov/I94. You can also look at your admission stamp in your passport to find out when your U status started.
You have to prove that you have been in the U.S. for 3 years. You need to give USCIS a copy of all the pages of all your passports. It’s important to renew your passport before it expires. If you let it expire it could cause problems. If you get a new passport, keep a copy of all of the pages of the old passport. If you travel outside the U.S., keep copies of all your old I-94 cards too. Also, file tax returns for each year you are in U nonimmigrant status and keep copies of your tax returns.
Keep other papers that show you have been in the U.S. for 3 years. Here are some examples:
- rent receipts
- school records
- employment records, especially paystubs
- other papers showing that you are in the U.S. that have your name and date on them.
Warning: If you have less than 3 years of U nonimmigrant status, talk to an immigration lawyer right away.
