To clarify my situation, I have been working as a US citizen expat in Beijing for over 5 years. I met my wife, a Chinese National early on, got married and have 2 kids. Now my job is asking me to move back to the US but my wife cannot come with me because she doesn’t have a green card. My kids however do have US citizenship. I see DCF is really meant for this purpose, but the Guangzhou consulate only has an email address and hasn’t responded to my answers to their questions. It’s been 3 weeks now. How much longer should I wait?
