Is it true that Mexico denied her re-entry? The source article doesn't say anything about that, and I'm not sure why it would happen - Canadian nationals generally have visa-free entry for short trips to Mexico.
Yes, the agent saying "We have to send you back to Canada" is because she wasn't allowed in Mexico. By default her tourist card would have only covered entry from from Canada. The first CBP agent almost certainly attempted to get her back into Mexico which is why it took "hours." If she already had a valid VISA for Mexico then the default would be to return her. The article doesn't even really make it clear that she flew to Mexico first and then tried to enter the US. To the uninformed it would seem she may have flown into San Diego or something. She wouldn't be able to return to Mexico on an asylum claim either of course.
Canadians don't need a visa to travel to Mexico though [1], assuming they won't be doing any work or studying. Going to the airport to go back to Canada is not work.
Yes, but if she HAD a VISA she would have been allowed to return to Mexico. She entered Mexico with a Temporary Tourist Card for entry from Canada to exit through the US with specified dates or less than 72 hours. That card became invalid when she left Mexico. The border agents most certainly tried to get her back into Mexico, but "denied entry into the US" is going to cause a manual administrative review in Mexico and that appears to have been denied. The only thing different under Biden / Obama would have been that she may have been processed faster because their was less backlog.
She gambled on trying to to game the immigration system and lost. It sucks but 12 days in custody isn't world ending. The most amazing part to me is people with no experience with "the system" find themselves incarcerated and think not eating sounds like a good idea.
Yep this person clearly tried to manipulate the system and had the gall to admit that in public because she knew some many ppl wouldn't care and would support her regardless. this comment thread is proof of that.
