Thank you very much MaryandMian and KHURRAM SERAJ for the information. I think i am pretty late to apply for the K-3 visa now as my wife's interview is in June. About a month and a half left. Hopefully everything goes OK inshallah. By looking at different people's responses, it seems that females are getting the visa same day or in about 1-2 weeks. Another question, I heard from some one that if the person is coming on PIA after the visa, they need the transit visa for UK because there is a stopover in Manchester UK. Called PIA and the person there told that if the US visa is stamped then pessenger wont need the UK transit visa, but if the visa is not stamped on the passport then transit visa is needed. If thats the case, is this I-130 visa stamped on the passport or not. Because if we need visa then I might start preparations for that also.
Thanks
