Hi Daphne!
Thanks for your response. Absolutely understand AOS causes room for concern, I was more wanting to check this was even allowed at all as I'm only just seeing that some other posters have done so. I had no idea switching from consular processing to AOS was even a thing until about 20 hours ago.
I guess it worries me the most that my husband and I will be apart from majority of the time whilst the CR1 is processing and with the way things seem to be going these days, it could take well over a year and going for a couple of weeks at a time, many times, will be very expensive. Plus, spending more time out of the US than in it will also need to be applied here. I know I'm not the only one in this boat, but my husband is active duty military and his schedule is a lot more fixed than mine so taking leave to come to the UK and visit me regularly isn't an option for us. Whereas I can come and go as much as I like in theory as I own my own business which enables me a lot of time freedom.
