When will American women/girls actually be able to apply for asylum in Canada or Mexico?

I’m very curious about this topic because there’s so much talk of when to escape and how/why (especially as it relates to the confines of the show). It’s certainly not endemic to the show, so I’m curious if we have to wait for a published set of asylum seeking guidelines (as published by our neighbors to the north and south), or in your mind, is there defining moment where published guidelines wouldn’t matter, but it’s like a clear beacon that things aren’t OK? I’m just thinking of not being able to have a bank account, own my house, vote, or work. Should we be waiting for a specific invitation or just a specific event?
