Germany Visitor Visa: Invite with National Visa

"A person who is living in Germany on a valid German national visa (D-visa) can legally write a letter of invitation for someone applying for a German visitor visa — even if they do not yet have a Blue Card or residence permit card in hand.

However, there is an important distinction:

✅ 1. Invitation Letter (Private Invitation) — ALLOWED

A simple/private invitation letter is allowed from anyone legally staying in Germany, including those with:

National visa (D-visa)

Student visa

Work visa (not yet Blue Card)

Job seeker visa

Family reunion visa

Au pair visa

As long as their stay is legal, they can invite someone.

This private invitation mainly states:

Who you are

Your legal status

Your address

Purpose of visit

Duration of stay

Relationship with the visitor

This is totally acceptable.

❗ 2. Formal Obligation Letter (Verpflichtungserklärung) — MAY NOT BE POSSIBLE

This is different from a normal invitation.

A Verpflichtungserklärung (financial sponsorship document issued by Ausländerbehörde) may not be approved if the inviter:

Is on a short-term visa

Has insufficient income

Has no residence permit card yet

Cannot show stable financial ability

Many foreigners on a national visa waiting for a Blue Card can still get it, but approval depends on:

Monthly income

Job contract

Length of legal stay

Proof of residence registration (Anmeldung)

If the Ausländerbehörde accepts your documents, they will issue it; if not, only a private invitation is possible.

⭐ Summary

✔ Yes — you can write a private invitation letter while on a national visa.

✔ This is fully acceptable for a German visitor visa application.

❗ But to issue a Verpflichtungserklärung, your income and local immigration office approval are required."
