General Terms and Conditions


1. Participation and registration

1) Participation in our courses is possible for all persons interested in education from the age of 18. In consultation with TANDEM Hamburg e.V., participation in our courses is also possible for younger persons.

(2) You can register via our online registration form or send us the registration form by email, fax or post or you can bring it to us in person.

(3) You will receive a written confirmation of registration by e-mail, fax or post within one week of receipt of your registration. Only then does your contract with TANDEM Hamburg e.V. come into effect.

(4) If you require a visa for your language stay, the contract with TANDEM Hamburg e.V. will only be concluded on the condition that you make an advance payment:

a) for a booking of up to 12 weeks a lump sum of € 560.00
b) for a booking of 13 weeks or more a lump sum of € 1,500.00
c) A share of € 200.00 of this advance payment shall be deemed to be a security deposit. If no contract is concluded (e.g. because a visa was demonstrably declined / refused), fees already paid minus the security deposit will be refunded immediately.

N.B.: In many countries of origin, the German missions abroad or the corresponding German authorities require proof of full payment of the fees. These exceed the amounts mentioned above. Paragraph c) also applies to these cases.
