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 has identified that you need to appoint a U.S.-licensed attorney because your domicile is outside the United States. Furthermore, the examiner has deferred the trademark database search until this requirement is addressed.
