I have almost 100 visas + residence permits in my passports.
I lived in 4 countries and traveled to 60+.
I have gone through residency process for myself in Schengen countries and Chile.
For my Chilean wife, we have gone through residency process for Turkey.
I assisted many non-Turkish friends for their residence in Turkey.
I know lots of interesting, small details, tips and tricks that is really really hard to understand just reading on the internet and it took me many years to learn by experience.
So, if you want to save lots of time and make things way easier, let's talk.
