How long do they last?
For the periods listed. Future periods can be included only up to three years after the date the IRS receives the form. A new form for the same tax matter can revoke earlier ones unless you tell the IRS to keep them.
How do you revoke one?
Send the IRS a copy of the form with "REVOKE" written across the top, signed and dated, or file a new form stating that earlier ones are revoked. A representative can withdraw in the same way.
Can a foreign owner use them?
Yes. A foreign owner of a US LLC can sign a Form 2848 so a US representative can deal with the IRS on the LLC's Form 5472 or the owner's Form 1040-NR. See filing US forms from abroad and who can represent you.
