If you plan to move to Luxembourg for work, study, or family reunification, one of the most important steps is obtaining the Temporary Authorization to Stay (Autorisation de séjour temporaire).
This document is often misunderstood. It is not a residence permit, but rather a pre-approval issued before you enter Luxembourg for long-term stay.
At WorkPermitCheck, we frequently see applicants confuse the temporary authorization with the final residence card. Understanding the distinction is critical to avoiding delays or refusals.
What Is the Temporary Authorization to Stay?
The Temporary Authorization to Stay (TAS) is:
• An official approval issued by Luxembourg authorities
• Required before applying for a long-stay visa (Type D)
• Mandatory for most non-EU nationals
• A prerequisite for obtaining a residence permit
Without this authorization, you generally cannot proceed with a long-term visa application.
Who Needs It?
Most non-EU/EEA nationals planning to stay in Luxembourg for more than 90 days must first obtain the Temporary Authorization to Stay.
It typically applies to:
• Foreign workers
• EU Blue Card applicants
• Intra-company transferees
• Self-employed individuals
• Students
• Family reunification applicants
EU citizens generally do not need this step.
How Does the Process Work?
The process usually follows this order:
1 Employer (or applicant) submits application for Temporary Authorization to Stay
2 Luxembourg Ministry reviews eligibility
3 Approval is issued in writing
4 Applicant applies for a Type D visa (if required)
5 Upon arrival, applicant completes local registration
6 Residence permit card is issued
The TAS is therefore the first formal approval step.
What Documents Are Required?
While requirements vary by category, applicants typically must provide:
• Valid passport copy
• Employment contract or admission letter
• Proof of qualifications
• Criminal record certificate
• Health insurance coverage
• Proof of accommodation (in some cases)
Incomplete documentation is a common cause of delay.
Validity Period
The Temporary Authorization to Stay:
• Is usually valid for a limited period (often 90 days)
• Must be used to apply for the visa within the validity window
• Does not itself grant the right to reside long-term
After arrival, the applicant must complete formal residence procedures.
Is It the Same as a Residence Permit?
No.
The TAS:
• Allows you to apply for a visa
• Does not allow immediate employment without further steps
• Must be followed by residence registration
• Is a pre-entry approval
The residence permit card is issued after arrival and registration in Luxembourg.
Common Mistakes Applicants Make
Frequent errors include:
• Applying for a visa before receiving TAS
• Confusing TAS with final residence authorization
• Submitting incomplete documents
• Missing deadlines
• Starting work before full approval
These mistakes can lead to rejection or delays.
Why Verification Matters
Since the TAS is the foundation of your legal stay, it is essential that:
• Employer sponsorship details are accurate
• Job classification matches permit category
• Documentation is consistent
• Eligibility requirements are met
Even small inconsistencies can cause refusal.
How WorkPermitCheck Helps
WorkPermitCheck provides independent verification support to help:
• Confirm employer compliance indicators
• Review documentation alignment
• Identify eligibility gaps
• Reduce refusal risks
• Ensure correct permit classification
We do not issue authorizations or visas. We verify authenticity and compliance indicators.
Key Takeaway
The Temporary Authorization to Stay in Luxembourg is:
• A mandatory pre-approval
• Required before long-stay visa application
• Not the same as a residence permit
• A critical first step in legal relocation
Proper preparation at this stage prevents complications later.
