Hello,

If you wish to switch to that type of card, a specific application has to be filed at the immigration office, including documentation that proves you have a private medical insurance and sufficient sources of income for the whole family.

Sources of income must be quantified using as reference 150% monthly IPREM minimum for a 2 member family and adding 50% per additional dependent.
Current monthly IPREM is 537,84 €. That is 806.76 € per month for a two member family, 1,065.78 € per month for a three member family.
