A short-stay Schengen visa allows Vietnamese passport holders to travel within the Schengen area — most EU countries plus some non-EU countries — for up to 90 days in any 180-day period. You apply at the consulate of your main destination and must show a clear purpose, sufficient means, travel medical insurance and an intention to return. This article explains the general principles; detailed rules, fees and documents change over time, so always check the consulate’s official website before applying.
What the Schengen area is
The Schengen area is a group of European countries that have abolished routine internal border controls. Once inside, you can travel from France to Germany or Italy to Austria usually without showing your passport at the border, although countries may run spot checks or temporarily reintroduce controls. The area includes most EU countries and some non-EU states such as Switzerland, Norway, Iceland and Liechtenstein.
Note that not every EU country is in Schengen. Ireland, for example, has its own visa policy, and the United Kingdom is in neither the EU nor Schengen. Membership can change, so check each country when planning.
The 90-in-180-day rule
This is the most misunderstood rule. You may stay up to 90 days within any 180-day period, counted backwards from each day you are present. It does not reset every 180 days. For example, if you stay 60 days and leave, then return within 180 days of the first day of your earlier trip, you may have only about 30 days left. The European Commission offers an online calculator so you can check.
Overstaying can bring fines, a record in the system and difficulties with future visas. Never take this rule lightly.
Where to apply
- One country: apply to that country’s consulate.
- Several countries: apply to the main destination, usually where you stay longest or the main purpose of the trip.
- Equal stays: usually apply to the country of first entry.
- Visa application centres: many countries outsource collection of applications; the decision is still made by the consulate.
Applying to the wrong country is a common reason for refusal. Your real itinerary must match where you apply.
What you usually need to prove
Each consulate has its own document list, but in general you must convince them of four things:
- A clear purpose: itinerary, accommodation bookings, an invitation letter for family visits, a business invitation, or conference registration.
- Sufficient means: bank statements, proof of income, property documents, or a sponsor’s guarantee.
- Travel medical insurance meeting the required minimum, valid across the Schengen area.
- Intention to return: employment contract, proof of study, approved leave, family and property in Vietnam.
A good application is a consistent one
Consular staff read huge numbers of applications. What they look for is consistency: leave dates matching travel dates, bookings matching the itinerary, bank statements showing stable income rather than a large sum deposited just before applying. A simple, honest and coherent application is usually more convincing than a thick file full of contradictions.
Timing
Under the general rules you can apply within a certain window before travel, and it is wise to apply early, because appointments fill up in peak seasons such as summer and year-end. Processing can take longer if more documents are requested. Do not buy non-refundable flights before you have the visa; many consulates accept a provisional reservation.
Biometrics and interviews
On your first application you will usually give fingerprints and a photo. These are stored in the common visa information system and can be reused for later applications for a period. You may be asked a few questions about your trip; answer briefly, honestly and consistently with your documents. Europe is also gradually introducing electronic entry and exit recording at borders, which may involve biometrics when you cross.
Travelling with children
Children need their own passport and visa application. If a child travels with only one parent or with other relatives, consulates often ask for written consent from the absent parent and copies of birth certificates. Requirements vary, so read the guidance carefully. Preparing these papers early avoids stress at the visa centre and at the border.
Other kinds of visa
The short-stay Schengen visa is only for tourism, family visits, business, conferences and short courses. For long-term study, work or family reunification you need a national long-stay visa from the destination country, with entirely different rules and documents. Never use a tourist visa to work; that is a serious violation.
If you are refused
Refusal letters usually give standard reasons, such as failure to prove purpose, means or intention to return. They also explain how to appeal within a deadline. Read carefully, assess your weak points honestly and add genuine evidence before reapplying. One refusal does not mean refusal forever.
Beware of scams
- Do not trust services that guarantee a visa; only the consulate decides.
- Never buy or use fake bank statements, contracts or invitation letters. False documents can lead to entry bans lasting years.
- Book appointments only through the official consulate website or authorised application centre.
- Watch out for fake websites charging high fees; official fees are published openly.
Once you have the visa
Check the details carefully: name, passport number, validity dates, number of days and number of entries. Carry copies of your accommodation, insurance and return ticket when crossing the border, as officers may ask. Following your itinerary and returning on time will make future applications much smoother.
Building a travel history
Many travellers find that the first Schengen visa is the hardest. Once you have travelled and returned on time, later applications are often easier, and some consulates may grant longer multiple-entry visas to applicants with a good record. Keep copies of previous visas and entry stamps, and treat every trip as part of a long-term relationship with the countries you visit.
What to remember
The Schengen visa is neither a mystery nor a matter of connections. It rests on clear principles: a real purpose, real means, proper insurance and an intention to return. Honest, consistent documents, an early application and regular checks of official information are the surest path into an open Europe.
Frequently asked questions
How long does a Schengen visa allow me to stay?
A short-stay visa allows up to 90 days within any 180-day period, depending on the number of days granted on the visa.
Which embassy should I apply to?
Usually the country that is your main destination, where you stay longest or which is the main purpose of the trip; if stays are equal, the country of first entry. Read the consulate’s guidance.
Do I need travel insurance?
Yes. Schengen applications generally require travel medical insurance meeting the minimum coverage set by the rules, valid throughout the Schengen area for the whole trip.
What if my visa is refused?
Read the reasons in the refusal letter, learn your right to appeal as explained there, and strengthen your documents before reapplying.
Should I use services that guarantee a visa?
No. Only the consulate decides. Never use false documents, which can lead to refusal and entry bans.
