hi everyone!

I did a PhD in Turkey in 2016, after 2 years of trying, I still have not found a job due to bad economical conditions here. I applied for Postdoc (with 6 published papers), unfortunately the options in my subject are very limited and I could not get one. I am now very disappointed.
Is it possible to apply for a second Phd elsewhere in Europe, (in another subject that I am interested in), so may be I can find a job after that? What if I don't tell my supervisor that I already have a Phd?
