We're ready to apply for her AOS ( for the 2 years conditional green card). She had the medical in China right before her visa interview, however, she didn't have a copy of the medical result. Since, she is holding a K1, so at that time the vaccination was not required. I wonder, during the process of applying for her greencard, do we need to send any medical result & vaccination proof? She has not had her vaccination done yet. Do we do that before apply for the AOS, or we do it before we have our AOS interview here in the states? Another question, on her SSN, social security card, it says that VALID FOR WORK ONLY WITH DHS AUTHORIZATION. What dose that mean? She donse't have a greencard now, is her condition as a K1 holder okay to work legally? We're married already. Thank you very much if any reply!
