“The new members must issue biometric passports, which are tamper-proof and difficult to forge, to their citizens. They also must agree to cooperate with U.S. authorities on security threats and other safety issues.”
That’s kind of vague. I’d like to know more about Poland’s immigration and naturalization laws. If they are too lax, undesirables will flock to Poland as a path of least resistance to the US; a stepping stone. That’s bad news for both Poland and US.
I know for a fact that the Baltics must send their people to the US Embassy in Warsaw to get their biometric and green card interviews.
I doubt that those countries are yet equipped to meet the new passport standards.
