I have been in the UK for about a year and six months now, on what was initially intended to be a six month trip. Got stuck here due to covid stuff, return flight cancellation, etc... It took me until just a month ago to get an interview for a returning resident visa, which was promptly denied. I didn't feel that I had an adequate chance to present my case and show my corresponding paperwork. So, can I apply again, or is that it? Should I seek legal representation at this point? Should I simply attempt to return to the US? I have been a green card holder, living in the US for over 15 years, and I remain married to a US citizen. What should I do? Please help!!!
