I can speak from both sides of doing immigration through both countries. Either way is confusing.
If it wasn't for this forum I would hire an attorney I had so many questions.
As somebody else mentioned the information we received from the biometrics was incorrect. It was outdated. Instructions to use Fed ex and the wrong dollar amount for the Priority service.
I feel the Priority is a rip off but then we got the visa in 6 days and I know people who mailed in May are still waiting. Really could not afford it though.
So we are all going to be a little grey haired, poorer and probably had one too many arguments with our husbands during this nail biting time.
Lol
Thinking of you all .... hang in there you are going to love the UK!!! I can't wait !!
