Your passport

If you are NOT a citizen of a Scandinavian country you must have a valid residence permit to a Scandinavian country if you wish to benefit from the services of consulates in Scandinavian countries.

Your passport must be valid at least 6 months.
It must contain an empty page (sometimes two adjacent empty pages)
It must not be broken, torn or illegible due to any circumstance.

Do not attempt to mix Israeli and arabic visas in the same passport.

Don't bring / send your passport in a surplus plastic cover.

If you are a frequent traveller with many visas to the same country, you may sometimes have to wait until the old visa is unvalid before the consulate gives you a new one.
