I live in Canada [Toronto] but work for a company in USA on H1B visa. My wife will be coming to live in USA on H4 visa. She will be living in Buffalo,NY while I will move from Toronto to Fort Eerie,ON. I am going to sponsor PR for my wife. Would there be any hiccups with me staying in canada on H1B [US visa working for US company] and she staying in USA on H4 [spouse of person working in USA].
