Important inquiry...

A travel document (advance parole) for multiple entry, which was applied few years ago, and was then approved and which now has expired;

is this document also auto-extended until 2022, or do we need to pay and reapply for being able to travel again?

It will be greatly helpful if someone could help clarify with references. Thanks in advance and best wishes to all.

For Travel document, you need to re-apply and pay a fee. The travel document must not be expired before you board the plane overseas.
