What happens if I overstay my visa?

No, you cannot be detained and deported immediately just for a two-week overstay — but you become an unlawful non-citizen and may be detained or removed after due process under the Migration Act.

If you overstay your visa in Ireland, you become an 'illegal immigrant' under the Immigration Act 2004 and may face deportation, a ban on re-entry, and restrictions on future immigration applications.

If you overstay your visa in Singapore, you may face a fine of up to $4,000, imprisonment for up to 6 months, or both — and potential deportation.

If you leave South Korea voluntarily while overstaying, you may avoid detention and criminal penalties, but you could still face a re-entry ban of 1–5 years depending on overstay length.

If you overstay your U.S. visa, you begin accruing unlawful presence, which can trigger bars to reentry (3-year or 10-year), make you ineligible for many immigration benefits, and subject you to removal proceedings.

If you overstay your visa in Japan, you may face deportation, a re-entry ban of up to 5 years, and possible detention. You must leave Japan immediately or apply for status regularization before removal proceedings begin.
