Question

Leaving UK,good Visa,Us citizen,the airport told him he overstayed he has to pay basic travel allowance. WHY?

Answer 1

They do the same in the US, i.e. Brits gets 90 days visa to visit the US, if one exceeded the time limit he/she will be find when leaving the state if it was few days, if more he maybe black listed, I'm sure we do the same here for US citizens.

Answer 2

Why should we have to pay for your travel home? You are the illegal immigrant who "overstayed".

Perhaps you would prefer that we take you out to the three mile sea limit, throw you overboard and tell you to swim home?

Good riddance to you.
