You can be granted an emergency alien’s passport if you have a particularly pressing and urgent need to travel to or from Sweden and cannot get an ordinary alien’s passport, travel document, or national passport. An emergency alien’s passport is a temporary passport that is only valid for a short period and for a one-way or return trip. If you can obtain a temporary travel document from the national authorities in your country of origin, you should contact them first.
The Swedish Migration Agency grants emergency alien’s passports on a restrictive basis, and it is up to you to prove that you cannot obtain any other travel document.
