Do this yourself in order to avoid any problems or extra costs arising when using your visa. If you think that the information on the visa sticker is incorrect, tell the consulate or embassy immediately, so that any errors can be corrected.
How to read the visa sticker
TRAJANJE BORAVKA (DURATION OF STAY)… DANA (DAYS) indicates the number of days you may stay in Croatia. The days should be counted from the date you enter Croatia (the entry stamp) to the date you exit Croatia
The period of time between „OD (FROM)... DO (UNTIL)“ is usually longer than the number of days printed in the TRAJANJE BORAVKA (DURATION OF STAY) field. The difference in period is meant to give you flexibility to plan your entry into and exit from Croatia, but your stay in Croatia must never exceed the exact number of days in the TRAJANJE BORAVKA (DURATION OF STAY) … DANA (DAYS)“ field. No matter how many days you have stayed in Croatia, you must leave no later than the date printed in the DO (UNTIL) field.
Controls at the border
Your short-stay visa allows you to travel ONLY to the Republic of Croatia, but in case you have Croatian visa valid for two or multiple entries, you will be able to enter Romania, Bulgaria or Cyprus. However, prior to visiting mentioned countries, please check possibilities with their respective embassies.
Holding a Croatian visa does not automatically entitle you to enter Croatia. So you may have to provide certain information at border or other controls. You may, for instance, have to provide information on your means of support, how long you intend to stay […] and why are you visiting […]. In some cases, such checks may result in a refusal for the visa holder to enter Croatia.
It is therefore recommended that you carry with you copies of the documents which you presented when you applied for the visa (e.g. copies of letter of guarantee, travel confirmations, means of subsistence and other documents proving the purpose of your stay). This will help to make the border control procedure easier and avoid delays at the border.
After arriving to Croatia you have two days to register with the police authorities according to your place of residence. Also, in case you change your residence during your stay, you have to register again within two days. A legal and natural person providing the accommodation to an alien (accommodation provider) shall register the accommodation of the alien on short-term stay within one day of the arrival of the alien for accommodation.
