Dear all,
I've had blue card since August 2016 valid for 4 years. I quit my job in Feb 2017, and found a new job recently. But I just realized that I did not notify the immigration office regarding the termination of my last job. Now as I have a new contract, can I just go to immigration office with my new contract, blue card to change the employer info? There is not my last employer's name on my blue card working permit, I wonder if immigration office would research on the termination of my last employment and reject my application to start my new job. What should I do?
Million thanks,
Nadja

HI,
Did you receive any additional sheet with your blue card?

In that it would be said clearly, If it was written, for the first 2 years change of employer should be informed to ABH. orelse you can continue your job with your employer. 

Anyway your change of employer would be already known to finanzamt. So, for good thinking about you, kindly inform ABH also before they find it.
