I am expecting to visit UK several times in next 2.5 years, staying for a period of 3 days to 6 months on any visit. I am employed in EU, for this whole time, with a contract. All my travels are paid by my employer. I also have invitation for all my visits from the partner company in UK.
I already have a 6 months regular visitor visa. I have traveled once (5 days) on it. But this visa would not suffice for all of my future travels, and I might need to apply again while on a visit.
I am thinking of applying for a long-term visitor's visa before leaving for UK a second time. My question is, how are the chances of getting it approved..?? Can someone please share experiences related to this, which might help me decide whether to take a chance or not..?
