The conversion of certain types of residence permits is possible only if they fall within the number established on a yearly basis by the Immigration Quota.
These types of residence perits can therefore, only be converted in determined periods of time and if they fall within the quota.
Permit conversions that can be carried out exclusively through the Immigration Quota are as follows:

• conversion from study or training purposes to a permit for subordinate employment or self-employment (the request must be submitted before the expiry date on the residence permit);
• conversion from seasonal employment to subordinate employment (starting from the second season);
• conversion from religious reasons to work purposes, for work activities different to those listed in art. 27 of the Consolidation Act on Immigration.
