急问8老师，收到field office发来的RFE，要求重新做医疗检查，30天之内递交。可是申请人目前不在美国，没办法检查，这种情况下只能给移民局写信申请RFE deadline延期么？
-They need to return to US to conduct the physical exam and submit the I-693 before the deadline. No choice because no extension for the response to RFE is available. Otherwise, their I-485 will be denied, and if so, it will affect them to return to US.
