819.01(d) Qualified U.S. Attorney Required for Applicant with Foreign Domicile 
If the applicant’s domicile is located outside the United States or its territories, the applicant must be represented before the USPTO by a qualified U.S. attorney. 37 C.F.R. §2.22(a)(20). See TMEP §601.01 and §803.05(a) for determining whether an applicant is domiciled outside the United States or its territories.
The TEAS Plus application form will require the attorney’s name, postal address, email address, and bar information in order for the application to validate. See TMEP §811.01 for additional information regarding the requirements for applicant’s attorney’s identification information. See TMEP §602.01(a) and §811.01 for submissions that include clearly invalid attorney identification information or the bar information appears valid on its face but is later determined to be invalid.
If the application includes this information, the applicant will not lose TEAS Plus status if the application is amended to clarify the information or to correct an inadvertent error.
