Response to USCIS Notice

If USCIS determined that they need additional evidence to adjudicate the visa or citizenship applications, they will issue a Request for Evidence (RFE). USCIS also issues Notice of Intent to Deny (NOID) if they determined that the applications are meritless.

To obtain approvals for the applications, it is critical that the applicants or petitioners submit sufficient and convincing responses to the RFE or NOID by the deadline designated by USCIS.

Our firm provides legal services to respond to the RFE and NOID, which are included in our services for a visa or citizenship application if our firm is retained to file the underlying application.


Waiver Application

An individual who is inadmissible to enter or stay in the U.S. due to certain activities that violate U.S. visa requirements or other relevant U.S. immigration laws and regulations must obtain a waiver of the grounds of inadmissibility to enter or stay in the U.S.

Depending on the grounds of inadmissibility, an individual must ask for consent to reapply (“permission to reapply”) before the individual can lawfully return to the U.S.

Our firm provides the following legal services to individuals who seek the waiver or permission to enter and stay in the U.S.:
