Sponsor change: visa, TRC, and work permit

In plain termsWhen the Vietnam sponsor changes — new employer, new investor, or a host that disappears — three layers can break at once: work permit, TRC (Temporary Residence Card), and visa. Treat it as a spillover event. Do not assume the new offer letter updates Immigration.

Start here — three checks

Name who the current sponsor is on the TRC and on the work permit. If they differ, that is already a failure.
If employment ended, assume the old permit is dying and the old sponsor has notice duties. Do not keep working “until the new card.”
Sequence new employer filing before you surrender the only lawful stay you still have — unless that stay is already invalid

Decision map

Signal	Lock now	If skipped
Resignation or termination dated this week	Old employer must return the permit on the statutory clock and notify Immigration. Get that in writing.	You look employed on paper at a company that already cut you.
New employer wants you to start immediately	New work-permit window is 10–60 days before start. Immediate start is usually unlawful.	You work for company B on company A’s residue.
TRC still shows the old sponsor	Plan a new card, not a sticker. TRC expiry and sponsor change are not “renewal.”	You hold a card that no longer describes your host.
You are between jobs with no new sponsor yet	Stay logic reverts to whatever visa residue you have. Do not invent a job-seeker status.	Overstay and illegal-work risks stack while you “network.”
Family TRCs were tied to your sponsorship	Map spouse/child cards the same week. Their stay can fall when yours does.	You fix your job and discover the family layer already failed.

Scenario triage

Scenario	Looks safe	Real risk
Clean move from employer A to B, both FDI	Both HR teams are “handling it.”	A’s revoke and B’s new issue overlap badly. You work a month with no valid permit.
Founder leaves own company to a new venture	I still own shares, so sponsorship continues.	Labour sponsor is the employing entity and the TRC host, not a share register.
Old company disappeared or will not sign	The new company can explain it to Immigration.	You need a documented break: revoke, notice, then a new file. Narrative is not a form.

Common wrong movesWhere people lose time on this exact question.

Starting the new job on the old permit because “it’s the same role type.”
Waiting until TRC expiry to mention the employer change.
Letting family keep using cards tied to a sponsor that no longer employs you.

If this fails, do this nextRecovery order — not a generic legal memo.

Stop work for the new host until that host is on a real labour file.
Document the old sponsor’s end (permit return / notice) even if they are uncooperative — record what you asked for.
File the new permit, then the new TRC, then fix family cards. Do not reverse that order without a reason.

Evidence to prepareChecklist before you file or walk in.

Old work permit (scan) and labour-contract end date.
Written notice of termination or resignation, and any permit-return receipt.
Current TRC both sides, sponsor name highlighted.
Visa symbol still in passport, if TRC is not in play.
New employer ERC and draft contract.
New work-permit or exemption route chosen (not “TBD after start”).
Family TRCs and whose sponsorship they list.
Entry stamps if you will exit/re-enter to reset stay — only if that is a real plan, not a rumour.

Published gapWhat we do not invent on this page.

Immigration Law requires sponsor notice when sponsorship ends. It does not publish a single day-count for how long an LĐ TRC survives after that notice. Do not invent a grace period. Move.

Common questions

What happens to my Vietnam work permit and TRC if I change employer?

The old permit is tied to the old employment. The TRC is tied to the sponsor named on it. A new job needs a new labour file and usually a new residence card. There is no silent transfer.

Can I work during the gap between sponsors?

Not on the old employer’s permit, and not on hope. Either you still have a lawful stay without work, or you wait for the new route. Gap work is how inspections start.

Does the new company just “add” me to the old TRC?

No. Treat sponsor change as a new card problem, not a renewal sticker. See the TRC-expiry logic: new card, not renewal.
