A Canadian woman says she missed an awards ceremony for her dad in Brazil after being denied entry to the United States because she apparently needed a U.S. visa. Ontario resident Nur detailed her stressful experience dealing with U.S. Customs and Border Protection (CBP) and United Airlines on TikTok. Flagged at U.S. customsNur says she arrived at Toronto Pearson International Airport around 4 p.m. for her 7:45 p.m. United Airlines flight. The university student says she was put in a waiting room and assured by a CBP officer that if she missed her flight, United Airlines would be responsible for rebooking and refunding it. "They didn't care," Nur told us.
