Alert: On Sept. 29, 2020, the U.S. District Court for the Northern District of California in Immigration Legal Resource Center et al., v. Wolf, et al., 20-cv-05883-JWS, preliminarily enjoined DHS from implementing or enforcing any part of the USCIS Fee Schedule and Changes to Certain Other Immigration Benefit Request Requirements rule (PDF).

While the rule is preliminarily enjoined, we will continue to:

  • Accept USCIS forms with the current editions and current fees; and
  • Use the regulations and guidance currently in place to adjudicate applications and petitions. This includes accepting and adjudicating fee waiver requests as provided under Adjudicator's Field Manual (AFM) Chapters 10.9 (PDF, 2.86 MB) and 10.10 (PDF, 2.86 MB).

For more information, please refer to the Federal Register Notice, dated Jan. 29, 2021.

Order an Index Search or Record Request

Check the Status of an Index Search or Record Request

How Does the Process Work?

Do you have a file number, if yes then you many want to consider and index search since one person may have multiple records and fine numbers. If you request a file by number then you receive copies of record of files. If you do not have a file number or want to do a request name index search, then you will either get a positive or negative response. If you get a positive response then the letter identifies files by number with instructions.
