Question for those who filled out 5535 for Montreal. My husband's interview is soon and we're going in with low expectations, expecting the 5535 and a long delay. He wants to fill it out in advance so he can quickly complete it once requested. He has his 15 year travel history for other countries, but not for the US. Is US travel required to? I tried searching, only found one Reddit post that someone said US travel is exempt, but I don't know if that is true. How can he get his US travel history? He lived in the US previously on student visa for his undergrad and graduate degrees before immigrating with his family to Canada and now I'm dragging him back here, hahaha. Any advice appreciated! Thanks!
