Single Permit Family Reunification Timelines

Hi everyone,

I’m looking for clarity on the 2025/2026 family reunification process for a B34 Single Permit holder. I received my Visa D in February 2026, and my family (spouse + 2 children) plans to apply on April 15th (within the 6-month priority window).

We are not applying at the exact same moment, but we intend to travel together to Belgium on July 1st.

Key Case Details:

Income Status: My gross monthly salary exceeds the new €5,000 threshold for Fast-Track processing.

Net Subsistence: My projected net income is well above the revised 2025 requirements for a family of four.

Permit Note: My Annex 46 specifically states that family visa applications must be forwarded to the Immigration Office in Brussels. Note sure if this a generic note for every single permit letters.

Timing: I will not have moved to Belgium or started my job yet when they apply on April 15th.

Questions for the community:

Applying Before Travel: Since I am applying within 6 months of my own visa issuance, do I legally need to travel first, get a permanent house, and wait for my first Belgian payslip before my family can apply? Or is the signed contract and SD Worx simulation sufficient under the new 2025 rules?

Forwarding vs. Fast-Track: If the Annex 46 says "forward to Brussels," does the 15-day Fast-Track for high-earners (over €5k gross) still apply?

Accommodation: Can we submit the application for family visas using a confirmed hotel/apart-hotel booking for our July 1st arrival, or is a permanent lease required at the time of the VFS appointment? And does 1 month hotel booking work?

Thank you
