We sent our I-129F via certified mail and we have confirmation that they received our application on the 27th of December.
Today is the 4th of January and we still haven't got an e-mail receipt from them and the money has not been cashed yet. (We added the G-1145 and the G-1450 on the top of our packet).
We also thoroughly checked the application before sending it to make sure that everything is correct.
Is anybody else experiencing a similar delay??
