How to Apply to Replace Your Green Card
If you are a permanent resident who needs to replace your green card or a conditional resident who needs to replace your two-year green card for any of the reasons listed below, you may begin the application process for a replacement green card by:
- Online E-Filing Form I-90, Application to Replace Permanent Resident Card.
- Filing a paper Form I-90, Application to Replace Permanent Resident Card by mail.
If you are outside the U.S. and have lost your green card, contact the nearest U.S. consulate, USCIS office or port of entry before attempting to file a Form I-90. If your Form I-90 application is approved, you will be mailed a replacement green card with a 10-year expiration date from the date it is issued.
