Hi Vinmer welcome to the foum. Visitor's visa is very hard to secure but i have applied and was just lucky to get one. It was my first time to travel and so i also heard that i will have a very slim chance of obtaining it. I submitted all the needed documents plus his sponsorship letter, payslips, bank statements. You may tell your gf to submit the docs on the checklist. Just try. Wish you the best of luck!
