Can my husband travel to the Netherlands ? He was convicted of raping his first wife in Massachusetts in the early 80ties. He served 2 yrs and 2yrs parole and probation afterwards

Europe is lots and lots of separate countries, each with their own rules. There will be some places he can not go, others he can.

Suggest contacting countries it is going to AS WELL AS the countries any proposed flight might land. As they can prevent his boarding as well.
