I have a B1-B2 visa (on my Venezuelan passport) that will expire Oct 12, 2019.
I will not renew that visa and will start using ESTA from now on (I am citizen of Spain also). My question is: When should I apply for ESTA? Before or after my B1-B2 visa expires?
I am traveling this week to the United States and I will travel again in September. Please let me know. Thanks
