I was married to an USC a week ago and am currently in status on a B-1 visa from Canada. I have spent winters in Florida for the last 25 years and have known my husband since then. I have always had my U.S mail delivered to my husbands address and have a residential address and p.o. box in Canada for my Canadian mail. I am unsure of which of these address to use or should I use both? Thank you in advance for any input!
