I have been offered compensation. How do I receive payment?

(Applies only to HIM Trimester Program participants)

You must sign your contract in order for us to initiate the payment process, so please come by our offices immediately after your arrival. You can expect the first payment approx. 1-2 weeks after signing. Subsequent payments will be available at the beginning of each month.
If you indicated cash as your payment preference, our Finance Officer will provide directions to the University Cashier´s office. If you provided your bank details, compensation will be credited to your account.
Please note: 1) our office cannot make compensation payments to you, and 2) your rent or security deposit obligations cannot be automatically deducted from your compensation.


Do I need a residence permit in Bonn?

Local law requires that guests who take up residence in an apartment must register their Bonn address with the municipal authorities within one week after moving in. Guests who lodge in hotels or pensions are not required to register (unless they stay 2 months or more). The logical consequence: you must de-register prior to your departure!
HIM administrative staff will help you complete the paper work. Getting your papers stamped at the Town Hall will not take long, but you must do it in person. Take your passport or ID with you.

The Town Hall address and operating hours:

Department ”Einwohnermeldeamt”
Berliner Platz 2
53111 Bonn

Mon and Thurs 8 a.m. to 6 p.m.
Tues, Wed, Fri 8 a.m. to 1 p.m.


How do I extend my visa after my arrival?

You must apply before your original visa expires, otherwise you will have ”illegal” status in Germany!

Ask HIM Visitors Office to make an appointment for you at the Bonn Immigration Office, whose special staff cater to foreign researchers and speak English. Attention: If your spouse or children accompany you, be prepared to provide a copy of your marriage license and the birth certificate(s) of your children.


Will HIM provide me with a workplace / office space?

(Applies only to HIM Trimester Program guests)

Yes, you can assume that HIM will provide a workplace for your approved and confirmed dates.
