I have lived in Germany with job specific Aufenthaltstitel for more than 3 years. I have worked in two companies in this time, and when I got hired for the second job I went to Ausländerbehörde and got a new Aufenthaltstitel with the new job specified as my work place.
My Aufenthaltstitel also includes the following line: “Selbständige Tätigkeit gestattet”
My Aufenthaltstitel expires in half a year.
I am considering joining an American company to work remotely and I'd like to register as a freelancer or self-employed, whatever fits, so I am able to issue invoices and pay tax here in Germany.
I understand that my current status allows me to be self-employed,
but I don't know if I can extend the residence permit being self-employed?
Any direction in terms and maybe sites where I could read about this would be greatly appreciated.
