Best Vietnam Visa Extension Services in 2026 (Da Nang and Central Vietnam)

A standard Vietnam e-visa cannot be extended once you’re inside the country - the only way to get a new one is to exit and re-enter, or reapply from abroad, per evisa.gov.vn’s FAQ. Most pages promising to “extend your Vietnam visa” are actually selling one of two things: a sponsor-based conversion to a new visa type, or a border run rebranded as an extension. I’ve run visa-run transport and e-visa processing out of Da Nang since 2019, and I hear the same question daily: can I just pay someone to extend my visa? It depends entirely on whether you have a sponsor in Vietnam, and that single fact shapes everything below, including why a visa run (my own daily bread) ends up being the realistic option for most readers.

1. Official DIY path - Vietnam Immigration Department

The Immigration Department is the only body that can legally extend a DL or DN visa, or process a sponsor-based conversion under Article 16. It costs the statutory $10 fee under Circular 28/2026/TT-BTC - but you need a Vietnam-based sponsor to open a file at all.

File form NA5 online at dichvucong.gov.vn or in person; eligible cases process in 5 working days. Da Nang’s office sits at 78 Le Loi, Hai Chau (desk at 7 Tran Quy Cap), open Mon-Fri 08:00-11:30 & 13:30-16:00, Saturday mornings only. Pros: real legal authority, zero markup. Cons: Vietnamese-language forms, a sponsor requirement that rules out most tourists, and missing your visa’s last valid day before filing turns this into an overstay problem too.

2. ANT Lawyers

ANT Lawyers is a Vietnamese law firm founded in 2012 with offices in Hanoi, Da Nang, and Ho Chi Minh City, where immigration is one practice area inside a broader legal practice. It fits a legal-structuring problem - a business partnership, an investor visa, a complicated sponsor case - better than a simple paperwork errand.

As a full firm, it can draft the sponsor agreement, handle a work permit alongside the conversion, and respond if immigration pushes back. Pros: licensed, physical Da Nang office, credible for complex cases. Cons: law-firm billing runs above a dedicated visa agency for something simple.

3. Vietnam-visa.com

Vietnam-visa.com is an online agency founded in 2007 that self-reports serving over 300,000 clients across e-visas, extensions, work permits, TRCs, and police checks, with urgent extensions advertised at around 4 working days.

One provider covers the whole ladder, so you don’t need to switch providers as your situation changes. Pros: long track record, broad coverage. Cons: runs online-only, with no walk-in Da Nang office, and the 300,000 figure is self-reported, unverified by any outside audit.

4. Vietnam Immigration (vietnamimmigration.org)

Vietnamimmigration.org publishes detailed Da Nang immigration-office guides and markets itself as budget-tier, with e-visa processing from around $6. It carries a 4.7-star rating from 23 reviews - a small sample, but a positive signal.

The Da Nang-specific logistics (addresses, hours, what to bring) beat most competitors’ generic pages. Pros: hyper-local info, low entry price. Cons: 23 reviews is too small a sample to lean on, and founding year and registration aren’t public - verify before paying for anything beyond a basic e-visa.

5. Global Vietnam Lawyers

Global Vietnam Lawyers (GV Lawyers) is a full-service firm with 60+ legal staff operating nationally. Like ANT Lawyers, it fits sponsor-based conversions tied to a business relationship - investor status, a corporate sponsor, a TRC bundled with a work permit.

Pros: staff depth for complex investor and corporate-sponsor cases. Cons: no visa-extension-specific pricing surfaces publicly, and the firm’s footprint reads Hanoi/HCMC-centric; Da Nang isn’t its base.

6. Vietnam Visa Pro

Vietnam Visa Pro sells rush e-visa processing, as fast as one business day, with a “guaranteed approval or money back” claim and a self-reported 5 million travelers served. It’s an e-visa speed service, separate from the extension and conversion services on this page.

Pros: fast e-visa turnaround, money-back framing. Cons: it doesn’t touch in-country extensions at all, the 5-million-traveler figure is unverified, and at least one public review called checkout “not 100% legit” - a data-handling caution worth weighing before you submit anything.

7. Local Da Nang visa agents / expat Facebook groups

Agents who post in groups like “Expats in Da Nang City” are a loose category of informal operators - no single company runs it, just people who DM after spotting a visa question in a public post. Some give real, useful advice for free; others run a documented pattern of asking for personal bank transfers with no invoice issued.

Unsolicited DMs, pressure to pay a personal account, zero recourse if someone disappears with your passport details - a recurring pattern across expat forums. Pros: free, sometimes accurate for simple questions. Cons: no licensing, no accountability structure, the highest-risk category on this entire list.

8. Best Bus (danangvisarun.com - us)

Best Bus has run visa-run transport and e-visa processing out of Da Nang since 2019. To be direct: we’re not an extension or conversion service - that’s the honest disclosure this whole page is built on. If you have a real sponsor (employer, spouse, business partner), a law firm above is the right call.

Once conversion is off the table, the option becomes what it was before the e-visa existed: leave and come back on a fresh one. We pay the e-visa fee with a card that evisa.gov.vn reliably accepts and keep the Lao Bao crossing to a single day. Pros: same-day turnaround, English/Russian support, a money-back guarantee - free reapplication and a refund if an e-visa application is refused twice. Cons: no extensions or conversions; a genuine sponsor situation belongs with a law firm above. What that fresh e-visa run actually includes is broken down on our Vietnam e-visa 90 days page.

How Should You Choose Between These Options?

Do you actually have a sponsor? A Vietnam-based employer, spouse, business partner, or investor status opens the extension/conversion path. No sponsor means a visa run is the practical route, regardless of what an agency’s landing page implies.

Is this a legal problem or a paperwork problem? A straightforward extension with a sponsor already in place just needs paperwork help - Vietnam-visa.com or the DIY route via dichvucong.gov.vn covers it. A conversion tied to a new business setup or a disputed sponsor relationship needs a firm like ANT Lawyers or GV Lawyers.

What is speed worth to you? The statutory fee is small (see the DIY section above); anything an agency charges above it is buying speed and English-language handling through Vietnamese bureaucracy.

Can you verify who you’re paying? A licensed firm or an agency with a real address and years of public track record is verifiable. A stranger’s Facebook DM asking for a transfer to a personal account is not - that gap is where most Da Nang visa scams start.

If you’ve read this far and landed on “I don’t have a sponsor, I need a visa run,” we rank the visa-run operators themselves the same honest way in Best Visa-Run Services from Da Nang, and that’s the gap Best Bus - danangvisarun.com exists to close: book a visa run, an e-visa, or a transfer directly on the site, in English or Russian, with a card that actually goes through. For questions before you book, message Telegram @learnx1000 and I’ll walk you through the timeline for your specific visa, or reach the same team on WhatsApp if Telegram isn’t your platform.

Frequently asked questions

Can I extend my Vietnam e-visa while I’m still inside the country? No. The e-visa (EV) category in use since August 2023 has no in-country extension mechanism - evisa.gov.vn’s FAQ confirms the only options are exiting and re-entering on a new e-visa, or applying for a new one from abroad before the old one expires.

What’s the difference between a visa extension agency and going directly to the immigration office? An agency handles the Vietnamese-language forms and liaises with your sponsor’s registered local office for you. Filing yourself through dichvucong.gov.vn costs the same $10 and is legally identical, but the portal has no English-language interface and no live help desk.

What happens if I overstay my Vietnam visa, and how much is the fine in 2026? Fines are tiered by duration, from roughly VND 500,000 for short overstays up to about VND 40,000,000 (around $1,519) for the most severe cases, per Decree 59/2026/ND-CP, effective 1 April 2026. An overstay of 16 days or more can trigger deportation proceedings, with a right to 48 hours’ notice first - see the exact fine by number of days before you assume you have room to spare.

Is it possible to convert my e-visa into a different visa type without a visa run? Yes. A Vietnam-based sponsor applies for you at the Immigration Department under Article 16 of the Law on Entry, Exit, Transit and Residence: a registered employer supports a work visa, a business partner a DN (business) visa, a spouse or relative a family visa. Legally it’s a new visa being issued, so the paperwork calls it a “conversion” - a legally separate process from an “extension.”

What’s the difference between a visa extension and a Temporary Residence Card (TRC)? An extension adds one to three months to an existing visa, up to a year for DN (business) visas. A TRC is a separate card valid for one to two years ($145) or two to five years ($155), issued in about 5 working days, and it still needs an underlying sponsor basis like a work permit, an investment, or a marriage - see our TRC step-by-step guide for all four eligibility routes.
