As a foreigner in Germany, getting a PR means freedom my the consistent stress of visa dependence.
In my case, I came to German in Jan,2014 on a dependent visa. This actually helped me cover the journey from ….. Dependent Visa (2014) —-> to Work Visa (2014) —→ to Blue Card (2015) —-> to German PR (2017)
If you are lucky enough to get a job offer that qualifies for a Blue Card, then its a very easy journey for German PR.
Dependent Visa (2014) —-> to Work Visa (2014)
In my case, I found my first job in July,2014. For this, I changed my dependent visa to work visa. Since my first salary offer was €36,000 annually, I could not qualify for the Blue Card. At that time, Blue card limit was €48,000 annually.
As a dependent visa holder, you have the same employment rights as your spouse at the time of writing this answer. This is way better than having a H4 visa as the spouse of H1B visa holder in USA.
Work Visa (2014) —→ to Blue Card (2015)
In 2012, while working in Singapore, my visa application was rejected despite having a new job offer. This incident left quiet a mark on my memories, since I was asked to leave Singapore within 30 days of rejection.
Due to this, I was clear that getting rid of Visa dependency was my focus. After a job offer from Amazon in 2015, I was above the required salary limit. Applying for Blue Card in Munich was a breeze. The process, took its sweet time, since my files has to come from Heidelberg.
Blue Card (2015) —-> to German PR (2017)
While working in Berlin by 2017, I completed the required time to qualify for the German PR. Knowing that all of the German processes take quiet a long time, I started my PR process 2–3 months before the actual eligibility.
Since I had a regular job, consistent salary and a good history in the country, my application was accepted. Applying for PR in Berlin at that time was the easiest German bureaucratic process ever.
Why you ask?
I could apply for PR through an e-mail!!!! It might sound petty for a foreigner but once you live and deal with German bureaucracy, you will know what I mean.
German PR process for me (at that time in 2017) was :
Send an email with the required application, documents
My documents were checked
2–3 months later, they got back to me over email, asking for more information n documents
Submitted those documents, over email
Got an appointment email (the same day!!!!…. I was expecting atleast a month before getting any reply)
Asked a German friend to accompany me
Went for appointment, went through normal formalities, replied some questions in German, paid the fees
Was told to collect the German PR card in 2–3 weeks. A paper document was given as a proof for this duration.
Collected my German PR card and have not looked back since. Job change was never a challenge on work visa or blue card. With German PR, its not even a thought. Set up and registered a company in Berlin in Jan,2020.
Having a German PR gave me the confidence & freedom to pursue bigger dreams than a job.
