Foreign technical workers staffed to plants on project cycles face the LD2 extension question after every issuance round. Understanding the procedure’s substance — a stay extension anchored to the work permit — keeps the employer from ever letting a worker slide into overstay.
The underlying condition: the work permit drives the visa
The LD2 visa is the visa of the work-permit-required labor category. Every stay extension in this category rests on a work permit still valid for the right position and the right employer. The correct cycle is therefore: check the permit expiry → extend the work permit if needed (processed in 10 working days under Decree 219/2025/ND-CP) → extend the LD2 stay/visa on the new permit. Reversing this order is the most common reason visa extension dossiers hang.
Dossier and filing place
- The stay-extension request form (NA5) confirmed by the sponsoring organization;
- The original passport with sufficient validity (the extended stay cannot outrun the passport) plus the current visa;
- The valid work permit (certified copy or original for comparison as the receiving authority requires);
- The sponsoring company’s legal documents when requested (usually only at the first engagement with the local immigration authority);
- Filing place: the immigration authority where the company is headquartered or the worker resides.
When to stop extending the visa and convert to a residence card
An LD2 visa can run up to 2 years, but each stay extension is usually granted in shorter stints, creating repetitive procedure burdens and forgotten-expiry risk. Technical workers with long-term contracts and permits qualify for a temporary residence card under the LD2 symbol (validity up to 2 years, under Articles 36–38 of the Entry-Exit Law): the card replaces the visa for all exits and entries, one procedure for the whole permit cycle. Employers should treat the first visa extension as the signal to convert to a residence card — unless the project is ending and the worker is about to leave.
Overstay risk — the new penalty framework from 15 December 2025
Decree 282/2025/ND-CP tightens overstay sanctions on a progressive scale (Article 21): from VND 500,000 for under 16 days to VND 40 million from 1 year, with possible deportation in serious cases. For technical workers on project rotations, overstay usually comes from the company tracking the (longer) permit expiry while forgetting the visa’s — one shared expiry calendar for both document types (permit and visa/residence card) is the cheapest way to eliminate this risk.
Frequently Asked Questions
Where is an LD2 visa extension filed and what does it contain?
At the immigration authority (the Immigration Department or the Immigration Division of the provincial/municipal police where the sponsoring company is based or the worker resides). Core dossier: the stay-extension request form (NA5), a valid passport with the current LD2 visa, the corresponding valid work permit, and the sponsoring organization’s documents. In legal substance, this is an extension of temporary stay under Article 35 of the Law on Entry, Exit, Transit and Residence of Foreigners in Vietnam — the stay is extended on the basis that the labor purpose continues.
How far before expiry should the extension be filed?
It must be filed and completed before the visa/stay expires — there is no automatic grace period. Safe practice: file at least 5–7 working days ahead to allow processing and any supplementation. Note the underlying condition: the work permit must remain valid across the extension period; if the permit expires at the same time, extend the permit first, then the visa — a visa extension based on an expired permit will be refused.
What is the fine for overstaying an LD2 visa?
Foreigners overstaying are fined under Article 21 of Decree 282/2025/ND-CP (effective 15 December 2025, replacing Decree 144/2021/ND-CP) on a time scale: under 16 days: VND 500,000–2,000,000; 16 to under 30 days: VND 5–10 million; 30 to under 60 days: VND 10–15 million; 60 to under 90 days: VND 15–20 million; the longer the overstay, the higher the fine, reaching VND 30–40 million from 1 year, and serious cases may face deportation affecting future entry.
