I know a guy that did the same thing (Europe but non EU country) and left for US. It was a smaller amount 7-8k EUR (about 10k USD at the time). Bank was sending him numerous letters trying to make him pay the debt or to try and reach some kind of arrangement/settlement. As he is not there and there's no response - the bank wen to court, court couldn't do anything as he's not responding. It took them a while to determine that he's not in the country so they completed the case without him (he could restart the case once he's back as he couldn't bring his defense in front of the court) and now with the judgment the bank took it to bailiff to try and find assets (he has none) and as there is none the bailiff had to close the case. This whole process took couple of years! The bank may restart the process for another 10years with bailiff if they suspect he's back or has any assets.
I also know people that go to UAE to work (ordinary jobs) and after 6 months the bank would allow them to take the
cash loan. They take the loan and do not
repay to the bank. The bank takes them to court (via a video link/mobile phone app!). They would claim in front of the judge that the money was used to support his family abroad of for the urgent surgery of a family member and that they can't repay the bank. The court orders him to pay court expenses and that's it and sometimes like 10% of the loan amount, something nothing... BUT this person is now blacklisted at UAE credit bureau in and no other bank in UAE would allow that person to open an account (and his bank would close the
bank account he had - so basically he won't be able to bank anymore in UAE). I know some that even stayed there after that. They just ask for their company to pay them out via check that they cash out at the machine and pay everything via cash or via exchange offices (bills) and some take the money and leave UAE and use it to restart their lives somewhere else. I forgot what's the amount below they won't open criminal case against you (not sure if it's 100k, 150 or or 200k AED but I can find that in a chat I had with one of the guys that did this). This is much quicker than in the previous case and would last a couple of months or so...
Generally speaking this is a bad idea and I would never advise anyone to do such thing.
But if you want to do it - make sure that you know what amount would not get a criminal against you (than as an offense or small court case).
