Samui used to give me a checklist but I was at UR Imm this week they have no such list (or didn't understand my request). Is there one? Should I just work of the Samui list assuming it's all the same? TYIA

My current US passport has a short version of my first name ex; Jon. Because I will be issued dual citizenship and a second passport in a European nation in my full birth certificate name ex; Jonathan, I am considering changing my US passport to have the same full birth name. How will it impact my retirement extension, banking and drivers licenses in Thailand if at all? Should I not poke the bear and just have two passports with different names? I am concerned my new EU Nation will have issues when I need to present my US passport for parts of their process hence the concern.
