IR-1 Visa - Filling out the current address while staying as a visitor in the U.S.

[BadCivilServant 10]

My USC wife moved from Niagara Falls to Orlando in April to satisfy the domicile requirement. For reasons of her health and the deplorable condition of our apartment (starting with the mould), it was necessary for her to move. I have four weeks' vacation from work which started recently and ends ends in late June. I tendered my resignation from my job effective the end of my vacation (for my own sanity, I was going to quit anyway, green card or no green card). 

 

I drove my wife down in April in my truck along with a U-Haul trailer. I then returned to Canada. For the month we were apart, she rented an apartment in Orlando and got herself a job and stayed in an AirBnB in the meantime. My I-130 was approved in April. I have just received the NVC invoice and will be paying it in the next few days. 

 

Last week, I made a second trip to Orlando, again with a second and final U-Haul load. I had no issues crossing the border along with the trailer, as I had my wife fill out the 3299 and I brought copies of her passport, SSN, etc. I reported to the customs officer that I was in the immigration process, particularly in the Visa processing stage. I told him I was on vacation from work. I planned to be in the U.S. at least six weeks, and that I would be returning to Canada. He accepted the fact that I had to go to Montreal for my interview as my guarantee I would be returning. 

 

Prior to leaving Canada, I changed my Ontario driver's license, auto insurance, Nexus and other details to my mother-in-law's address (also in Ontario). I am effectively living with my wife in Orlando. We are living off of our savings and my vacation pay, which runs out in mid-July. I am not working while I am in the U.S. We can meet our obligation until mid-September. Once I have my consular appointment date, I will return to Canada a few weeks prior, get my medical, stay with my mother-in-law, pay a modest rent to her and earn whatever income I can while I am back in Canada. If my interview doesn't happen before the end of July, I will return to Canada (again, to my mother-in-law) and wait out the process there.

 

All this leads up to my question: On my visa application, should I report the address I am "staying" at in Orlando as my current address? My name and my wife's name are on the lease. Or should I report my mother-in-law back in Ontario as my "current" address?

No your current address is in Ontario. You are just visiting Orlando.
