Hello,
I'm from Ukraine. My wife is also from Ukraine, but she was studying and working as doctor in Germany and had residence permit, so we have been married since 2012. During our marriage we had two children in the Germany.
since 2013 I have been living and working in the Germany, holding a document with the right to live and work (AUFENTHALTSTITEL). Due to family circumstances ( mother's serious illness and disagreement with my ex-wife), I arrived in Ukraine in December 2016 and since then I have had to travel to the Germany three times to visit the children and arrange their documents, but as mentioned above, As a result of violating the six-month border crossing visa regime, I was no longer able to extend the term of my document (right to live and work).
We got divorced in 2019 year due to a disagreement with my wife. Based on a court decision of Ukraine.
After divorce she's trying to restrict contact with my children, not answering my calls and etc. She's calling when she wants, maybe 1 time in month or 2 month.
Please help me how can i get Residence Permit back ? How to allowing me to have regular and uninterrupted relations with my minor children.
