My friend got her visa stripped and given a 10 year ban under Obama because of jokes in her text messages about a GC marriage. She didn’t get thrown in jail but she was refused entry back into the US and had to get someone to sell all her stuff while she flew back to her home country.
Most of you have no idea about how life is because you’re probably citizens but this is the reality at the border. It’s even worse in other countries.
Someone I know is from Australia and she said if you overstay your visa they track you down, arrest you and send you to jails outside of Australia mainland until you are eventually deported. Every country treats their border extremely strictly.
CORRECTION: I pinged my friend and I was wrong. They arrest them but don’t send to offshore jails. Those are for illegal immgrants that arrive on boats.
