Ask for help in applying for German D-type visa

1. The German D visa can only stay in Germany. Of course, you can go to France by train or car. If you take a plane, it is theoretically not possible, unless the customs makes a mistake.

2. Just get the residence permit and there is no need to apply for a Schengen visa.

3. If found and sent back to Germany, there may be a fine.

4. You still need a visa to go to the UK with a residence permit, but it will become very easy.
