Did you get the receipt in the mail or did it get uploaded online to your case? I sent in my K3/I-129F about 2 weeks ago and haven't heard anything yet. Mine also got sent to the Texas Service Center.
How long were you waiting for the I-129F/K3 approval from the moment you sent it in? How long did it take for that to get processed. Following that, how quick was it until your spouse was able to move to the USA?
