Firstly, Thanks to Bob for the pertinent information.
I'm sure it will be nerve-wracking for some Expats:
For starters, it shows the PRP has been cancelled on the death of a spouse or divorce in the past: "There were cases of cancellation a permanent resident permit under mentioned grounds (death or divorce), but courts abolished such illegal decisions of an authorized body." But the lawyer seems to indicate that this is not done now ( court decision, statute or executive order would be useful to have and read ). It's Ukraine, hopefully all offices got the same memo. Hopefully, the opinion is based on some discernible law; rumor doesn't hold water in court.
The second thing is the bit about your "your living address of origin," which means nothing in the English language but is similar to other translated gobbledygook I've seen in Ukraine. ("--- applying for PR obliges you to present prove of your living address of origin ---" What?!!! Huh?). Maybe it means the address of your permanent residence in your native country? And what kind of proof? Passport? DL? Lease agreement? Deed?
Still, thanks Bob. Good someone checked.
