Temporary Residence with a Blue Card
Highly qualified foreign citizens wishing to pursue employment in Germany that corresponds with their qualifications can obtain an EU Blue Card.
The EU Blue Card is only issued initially for a maximum of four years. If your employment contract is for a period of less than four years, you will obtain the EU Blue Card for the duration of the employment contract plus three months.
If you have held an EU Blue Card for less than twelve months, you must inform the Immigration Office of your change of employment. The twelve-month period begins when you take up employment. Periods of employment that have already been acquired outside the period of validity of the EU Blue Card can be included in this twelve-month period. The Immigration Office can also refuse the change of job retrospectively if the requirements for the issue of the EU Blue Card are not met.
If you have held an EU Blue Card for more than twelve months, you do not need permission from the immigration authority to change jobs. You also do not need to inform the immigration authority. The requirements for obtaining an EU Blue Card must be met each time you change jobs. Taking up self-employment is still not permitted.
