  3. Communicate: If you have any concerns or questions, reach out to the USCIS or your immigration attorney to clarify any doubts and keep your application on track.

How to ensure your application is processed as quickly as possible

In cases where your application has taken significantly longer than expected, and your attempts to address the issue with USCIS yield no results, you might consider filing a writ of mandamus. A writ of mandamus is a legal action that can push USCIS to make a decision on your case.
