Status 641 means the USPTO mailed a non-final Office Action identifying issues with your application. You typically have three months to respond with arguments, amendments, or evidence. Missing the deadline can abandon the application.

The examiner requires a U.S.-licensed attorney to represent you because your domicile is outside the United States, and has deferred the review of your application pending administrative review due to your previous attorney.
