Processing Times and Document Replacement Applications

The U.S. Citizenship and Immigration Services website has a web page with the heading USCIS Processing Time Goals. If you need to replace your legal permanent resident alien card you must file an I-90 application. The estimated processing time is currently 5.8 months although there is variation with location.

If you need to file an N-565 application to replace a certificate of citizenship you face an average estimated processing time of six months.
