When your visa is approved, the embassy or visa centre prints a sticker into one of the blank pages of your passport. For a Schengen visa this is a uniform, EU-wide format; for a UK visit visa it is a pink-and-blue vignette that now usually acts only as your entry token before you switch to a UK eVisa. Every airline check-in agent in Dubai, Abu Dhabi and Sharjah, and every immigration officer at your destination, reads these fields. If you cannot read them yourself, you are trusting that everyone else got it right — and small misreadings cause real problems, from being offloaded at the gate to being counted as an overstayer.
For UAE residents there is an extra layer: you often hold a passport from one country, a UAE residence visa in another document or on your Emirates ID, and a travel visa for a third country. Knowing exactly what your sticker permits keeps those three things from contradicting each other.
A Schengen sticker has labelled boxes. Here is what each one means in plain language.
This shows where you may travel. If it says Schengen States (or “Etats Schengen”), you may enter all countries in the Schengen Area. If it names specific countries or shows a code such as FRA with a minus sign, your visa is territorially limited — a restriction called an LTV visa — and you may only use the listed countries. UAE residents sometimes book a multi-country trip on a visa that only covers one state; always check this box first.
Marked as 1, 2 or MULT. A single-entry (1) visa is used up the moment you leave the Schengen Area, even if dates remain. Multiple-entry (MULT) lets you come and go. If you plan a side trip out of the zone — say back to Dubai mid-trip — a single-entry visa will not let you return. Our guide to Schengen visa validity explains how to request longer multiple-entry validity.
This is the single most misread field. It shows the maximum number of days you may actually spend inside the zone — for example 30 days — and it is not the same as the validity window. You could hold a visa valid for six months but be allowed only 30 days of presence within it. Track your days with our Schengen 90/180-day calculator so you never overstay.
These two dates are the window inside which you may use the visa. You cannot enter before the From date, and you must have left by the Until date. The number of days you may stay (above) must fit inside this window.
These must match your passport exactly. A mismatch — even a transposed name order, which is common for South Asian and Arabic names — can cause boarding refusals. If anything is wrong, contact the issuing centre before you fly.
The free-text box may carry codes such as the visa type or purpose. If it references a sponsor or a specific reason for travel, keep your supporting documents with you.
A UK visit visa vignette is simpler. The key lines are the valid-from and valid-until dates, the number of entries (visit visas are normally multiple entry), and the endorsement — for example “Visit” — which states the category. Since the UK moved to its eVisa system, the sticker often only covers a short window to let you enter the UK once, after which your immigration status lives in your online eVisa account. UAE residents applying from Dubai should read both the vignette dates and their eVisa carefully. For the full requirements, see our UK visa from Dubai guide.
At the foot of the sticker (and on the photo page of your passport) sit two rows of capital letters, numbers and chevron characters. This is the Machine-Readable Zone. It encodes the document type, issuing country, your name, document number, nationality, date of birth, sex and expiry, plus check digits that let a scanner detect a mis-read. When an officer swipes your passport, the machine reads the MRZ — not the pretty printed fields — so the two must agree. You do not need to decode it yourself, but if the MRZ is smudged or damaged, machines may fail to read it and you can face delays. This is one reason a damaged passport should be replaced before travel, a point covered in our passport validity and blank-page guide.
The mistakes we see most often at our Dubai office follow a pattern.
| What people assume | What the sticker actually says | Why it matters |
|---|---|---|
| “My visa is valid 90 days, so I can stay 90 days.” | Duration of stay may be far shorter than the validity window. | Staying to the Until date instead of the allowed days is an overstay. |
| “Single entry is fine, I’m only going to Europe once.” | A quick hop out of the zone (UK, Turkey, home to the UAE) ends a single-entry visa. | You cannot re-enter Schengen on the same visa. |
| “Valid for Schengen means every European country.” | Ireland, and non-Schengen states are separate; LTV visas cover only named countries. | Entering the wrong country can mean refusal at the border. |
| “The name is close enough.” | Name and passport number must match the passport MRZ exactly. | Airlines can refuse boarding in Dubai before you even fly. |
If you are unsure how to count your days, our visa timeline calculator and 90/180-day calculator do the arithmetic for you, and our refusal reason decoder explains letters if something has already gone wrong.

No. The From–Until dates are the window in which the visa can be used; the “duration of stay” is the maximum number of days you may actually be present. Always follow the shorter number of days, and count them with a 90/180 calculator for Schengen.
MULT means multiple entries — you may leave and re-enter the Schengen Area as often as you like within the validity window, as long as you do not exceed your allowed days. A “1” means single entry, which is used up the first time you leave the zone.
Most UK visit visa applicants from the UAE still receive an entry vignette valid for a short window, then manage their status through an online UK eVisa account. Read both, and carry evidence of your eVisa when you travel.
It can be. The name and passport number on the sticker should match the passport’s machine-readable zone exactly. If they differ, contact the issuing visa centre before flying, because airlines in Dubai may refuse boarding on a mismatch.
The Machine-Readable Zone is the two lines of code that immigration scanners read automatically. It repeats your key details with check digits so machines can verify them quickly. If it is damaged or unreadable, you may face manual checks and delays, so replace a damaged passport before travel.
