Someone else can promise to cover your costs in Germany
A Verpflichtungserklärung lets a relative, friend, or business already living in Germany take on your subsistence, medical, and return costs — but the authorities examine your host, not you, and it isn't always the right route for a student visa.
Almost every month, COSMA hears a version of the same question from a family in Dar es Salaam or Nairobi: "My cousin lives in Germany — can he just sign something so I can come?" The honest answer is yes, sometimes. The document is called a Verpflichtungserklärung, a formal obligation letter, and it's one of the least understood pieces of the German visa system.
One signature, four financial responsibilities
Signing a Verpflichtungserklärung is not a formality — it's a legal pledge. The host agrees to cover the visitor's entire livelihood for the length of the stay: subsistence (food, clothing, everyday costs), accommodation, medical and nursing care, and, if it comes to it, the cost of returning home. The German Foreign Office doesn't take the host's word for it either. Before the letter is issued, the local Foreigners Authority examines the host's income, savings, residence status, and living situation to confirm they can actually deliver on the promise.
Short visit or long stay — it isn't one-size-fits-all
There are two kinds of declaration, and mixing them up is the most common mistake. The short-stay version backs a Schengen visa — visiting relatives, attending a conference, sightseeing, anything under 90 days. The long-stay version backs a German national visa, and this is the one that matters for students: it can cover a language course, a study-preparation programme, a full bachelor's, master's or PhD, or even the up-to-six-month job-seeker period after graduation. One thing it can never do, in either form, is stand in for a family reunion visa.
The numbers behind the paperwork
Declaration of commitment vs the blocked account
Most COSMA students finance their studies through a blocked account (Sperrkonto): money in their own name, released month by month, that doesn't depend on anyone else's paperwork. A Verpflichtungserklärung is a real, legal alternative — but it shifts control to a third party. The Foreigners Authority isn't examining you anymore; it's examining your host's payslips, tenancy, and residence permit. If any of that falls short, the application stalls, and there's little you can do about it from Tanzania or Kenya.
Two ways to prove you can support yourself
- You open and fund it yourself — no dependence on a host's job or paperwork
- A fixed required amount, set annually, released to you monthly
- Accepted for every long-stay study visa, with no examination of someone else's finances
- Needs a host who is a legal resident with proven income or savings
- The Foreigners Authority examines the host, not the applicant
- Cannot be used for family reunion visas, and only the host's local office can issue it
Not every host qualifies
Having a relative in Germany isn't enough on its own. The Foreigners Authority checks the host against a fixed set of conditions before they're allowed to sign — and it's worth knowing these before a family starts planning around a host who won't clear the bar.
What a host has to prove
Clear travel dates
The visitor's arrival and departure dates must already be set before the host applies.
Financial competence
Proof of enough income or savings to cover the visitor's full maintenance — payslips, employment contracts, tax assessments, or business accounts, depending on how the host earns.
A registered German address
Shown through a registration confirmation or a landlord-backed rental contract.
Legal residence beyond the visit
If the host is a foreign national, their own residence or settlement permit must stay valid well past the visitor's planned stay.
A personal appearance to sign
The host normally signs in person at their local Foreigners Authority; someone else can only stand in with a notarised Power of Attorney and a copy of the host's ID.
Two more details are easy to miss. The original letter is the only version German consular services abroad will accept — if it's lost, there's no reissue, only a fresh application and fee. And the host's obligation doesn't run indefinitely: it ends the day the visitor leaves Germany, or the day they're granted a residence permit for a different purpose than the one they came for.
A Verpflichtungserklärung is real leverage if you have the right host — it can even carry you through a full degree without ever opening a blocked account. But it hands a piece of your visa outcome to someone else's paperwork, so it's worth weighing against the routes you control yourself before a family commits to it.
Check the current rules with the official sources
Fees, income thresholds, and validity periods are set by German authorities and get updated from time to time — this guide reflects the rules at the time of writing, not a substitute for checking directly. Before a host applies, or a family commits to this route over a blocked account, confirm the current requirements with:
- Federal Foreign Office (Auswärtiges Amt) — official Verpflichtungserklärung FAQ, covering validity, revocation, and the underlying law (§§ 66–68 Aufenthaltsgesetz)
- Make it in Germany — Securing funding for your studies, the federal government's English-language portal comparing the blocked account and the Declaration of Commitment
- German Embassy Dar es Salaam — guidance for hosts submitting a Verpflichtungserklärung, the specific mission most COSMA families will be dealing with

Every case is assessed individually by the relevant German Ausländerbehörde or consulate — always confirm your specific situation with them, or with a licensed advisor, before making financial or visa decisions.
