What are the visa & residency requirements in Andorra?

"Visiting and residing in Andorra requires certain entry requirements for foreigners. When applying for a visa for short-term stays, applicants must submit a valid passport, as well as proof of income, health insurance, and return flight tickets. Tourist visas for short-term stays up to 90 days are usually granted fairly straightforward. For longer stays, applicants would need to provide further documentation that is specific to the intended purpose of their stay. For foreign citizens who wish to reside permanently in Andorra, they must possess both a valid passport and one or multiple of the following: a valid work contract, proof that they are enrolled in a school or university, proof of pension/retirement, proof of financial means, or an invitation from an Andorran resident. In addition to these documents, foreign citizens will also need to demonstrate sufficient knowledge of both Catalan and Spanish. The residency process then requires that applicants be successfully registered with the local authorities in order to obtain the necessary entitlements and permits," said another expat in Andorra.
