U.S. Citizenship and Immigration Services (USCIS) announced on February 25, 2022, that for all H-1B and H-1B1 petitions received on or after April 1, 2022, USCIS will no longer accept a single, combined fee payment when Form I-539, Application to Extend/Change Nonimmigrant Status; Form I-765, Application for Employment Authorization; or Form I-824, Application for Action on an Approved Application or Petition, is filed together with an H-1B or H-1B1 petition (Form I-129, Petition for a Nonimmigrant Worker). Each of these forms received by USCIS on or after April 1 must have its own fee payment instrument or USCIS will reject the entire package. Only the fee for Form I-907, Request for Premium Processing Service, may be combined with the fee for a concurrently filed Form I-129 requesting H-1B classification, USCIS said.
USCIS explained that it is transitioning to electronic processing of immigration benefit requests. As the agency completes this transition, it will be using multiple systems to receipt and process various types of immigration benefit requests. Because H-1B and H-1B1 petitions and related applications are not all processed in the same system, USCIS said it requires a separate payment instrument for each of these forms.
