Job Seeker permit visa in Berlin

Here is the official German government website with information about visas:

To your questions: I have to first state that an American can stay 90 days for tourism upon entering the EU. This is visa free and not technically a tourist visa. The job seekers visa is not a job permit in itself. It just gives you permission to look for work. If you get an offer then one usually will then be given the work permit if you were able to qualify for the job seeker permit. If you find a job in another country in this time then you still have to apply for a work permit there. Having gotten a job seeker visa in Germany will not guarantee you anything in another country. I've never heard any limitations that you couldn't leave Germany during the time you are on the job seeker visa but that means you have less time to find a job.
