Hi , just filling out i130 form (I am UKC and wife is USC filing for me) , question 15 'name and address of present employer (if any)' is that solely to be filled in if I was already living in the USA? (We both live and work in the UK at present). Thanks in advance James

No, it's your current employer. As long-term denizens of this board will tell you - just take the questions at face value and answer them as such. Don't try to fit the question to fit what you think the answer should be - just answer what is asked.
