Hi and welcome to the forum
I wouldn't worry about forms and paperwork yet if you've only just started a friendship. I'f you've not been over there yet, my advice is to get yourself out there as soon as funds permit and meet her and her family, see her environment, how she is at home and see the country before you even consider any form filling. I've been back and forth many times in the last 2 years and still no nearer filling any forms in
