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 clarify your U.S. domicile address by providing supporting documentation or appointing a U.S.-licensed attorney.
