Yes, it is possible to sponsor a spouse using a Dutch PhD employment contract before receiving your first payslip. The Immigration and Naturalisation Service (IND) generally accepts a signed employment contract as sufficient proof of income, provided it meets the minimum income requirement for sponsorship. However, you may need to submit additional documents to demonstrate the contract is valid and the income is ongoing.

To proceed, you will need a signed contract from a recognized sponsor (most Dutch universities are recognized sponsors) that shows a gross monthly salary at or above the applicable threshold. For 2024, the standard income requirement for a partner is around €2,100 gross per month. PhD contracts typically meet this, but check the exact amount. You must also provide proof of your identity, your spouse's identity, and evidence of your relationship (e.g., marriage certificate). The IND may ask for your employer's confirmation that the contract is still active if you haven't started work yet.

A key tradeoff: While the IND can process the application with just the contract, some caseworkers may request the first payslip as a precaution, especially if the contract is conditional (e.g., pending a visa or residence permit). This could delay the process by a few weeks. To avoid this, ask your employer for a letter stating the contract is unconditional and the start date is confirmed. Also, ensure your employer is a recognized sponsor; most Dutch universities are, but check the IND's public list.

Concrete next steps: 1) Gather your signed PhD contract, a copy of your valid residence permit (if you already have one), and your spouse's passport copy. 2) Check the IND website for the current income requirement and application form (MVV for entry or VVR for residence). 3) Submit the application online or at an IND desk. 4) If asked for a payslip, provide it as soon as you receive your first salary. The IND typically decides within 90 days, but it can be faster.

A final honest note: If your contract is part-time or has a probation period, the IND may scrutinize it more. In that case, consider waiting for the first payslip to avoid rejection. Always verify the latest requirements on the IND website, as rules can change. This process is straightforward if your contract is clear and your employer is recognized.
