It has been two months since my girlfriend applied for my American fiance visa, but the embassy has never sent me a letter. What should I do?

The only way to check the progress of the document is to purchase the transportation card of CITIC Bank in 36 yuan or 54 yuan, and check with Shanghai Transportation Center. The telephone number provided by the consulate is only for emergency use, which is similar to inquiring about your immigration process and only leaving you a fax number. You can check with the consulate by letter or email. If it is an email, the consulate will reply within 5-7 days. But personally, I think two months is not too late. I suggest you wait 1 month.
