Family reunification processes in Europe vary by country but generally involve a visa application process for family members to join a resident or citizen, followed by a residence permit application after arrival. 

Here's a general overview:

1. Visa Application:

• Eligibility:

  The specific family members are eligible for reunification (spouse, children, parents, etc.) and the requirements vary by country.

• Documents:

  You'll typically need passports, marriage certificates, birth certificates, and potentially income or housing proof.

• Application:

  Complete the visa application form, schedule an appointment with the relevant embassy or consulate, and submit the required documents and fees.

• Processing Time:

  Processing times can vary, so it's recommended to apply well in advance. 

2. Residence Permit Application:

• After Arrival:

  Once your family members arrive, they need to register with the local authorities (e.g., the Residents' Registration Office).

• Permit Application:

  Before the visa expires, apply for a residence permit from the local foreign authority.

• Documents:

  You'll need to provide passports, birth and marriage certificates, pay slips or tax statements, rental evidence, and other documents as required.

• Employment:

  Once the residence permit is issued, some family members (like spouses) may be entitled to work without restrictions.
