Vietnam Visa in Hong Kong
People travelling on a Hong Kong passport need a visa to visit Vietnam. Until 1st July 2016, U.K. and certain other European passport holders do not need a visa as long as their stay is not more than fifteen days and they do not re-enter Vietnam within thirty days of leaving it for the first time.
Visa in Hong Kong
You can apply in person at the Vietnamese consulate. It is at 15/F, Great Smart Tower, 230 Wan Chai Road, Wan Chai (telephone 2591 4510, open Monday-Friday except public holidays, 9 a.m.-12.30 p.m., 2.00 p.m. – 5.00 p.m.). You can download the application form from the consular site here. As well as a completed application form, you need to take a 4cm x 6cm photo. For a three-month visa you need proof of return air tickets, as well as (for new Chinese mainland passports only) an extra photograph.
The visa will have a validity of three months from the date of issue.
You can get a one month single entry visa, one month multiple entry or three months multiple entry. The fee for the one month single entry visa is HK$640 for HK passports for the standard service, which takes a couple of working days. An express service is available at higher cost. Note that this is more expensive than using the visa on arrival process, discussed below. You need to pay in cash when applying – the consulate may let you pay on receipt but only if you argue with them.
When I went to the consulate on a weekday afternoon recently the waiting time to apply was around forty five minutes although in the early morning it was only around ten minutes.
Visa on Arrival
You can get a visa on arrival by air at certain airports (Ho Chi Minh City, Hanoi or Da Nang) . For other airports or arrival by train, land or sea it would be best to get the visa in advance at the consulate.
For the visa on arrival, you still need to apply before arrival and have an invitation letter. This is usually done by applying to any one of a number of visa agents, so the process ends up being similar to the e-visa process described below. Agents may charge different prices.
You can also apply online for an e-visa. The visa types are the same as above. The processing time is said to be approximately two days although rush options are available.
The e-visa seems to be a service provided by visa agencies, who are not officially affiliated to Vietnamese government but presumably have some links to it. You can easily find a wide range of such agencies online and may also see reviews of them, although remember that those which describe themselves as “official” are not part of the Vietnamese government.
