Thanks for all the help, wanted to let you know we entered Lviv on Friday with no issues. 2 different border agents checked Blue Cross insurance and we had no problems. About 6 border agents checking papers in terminal before you get to passport check. No questions at all, checked insurance and vax card. They were allowing those without insurance to purchase it online. At passport check the border agent checked passports and then asked for vax cards and insurance. Again not even one question. Not sure what this means for others, but we had no issues.
Only issue I had was a person from LOT airlines at Newark airport trying to tell me US citizens were not allowed in Ukraine, needless to say it was escalated to a manager and I was allowed through. I have no clue what this was about, even others on line behind us were saying she was wrong. I think she just didn't understand the rules, I have had others from LOT airlines at baggage check ask for my Visa, my response was simple. Don't need it, they check and apologize. If recall correctly they have asked for my Visa twice in the past.
Thanks for all the help we made it to Ukraine with no issue.
