Understood, and what Yuna was saying! Just worth an ask as I wasn’t sure, and saw mixed results when searching online. Thanks both. The VWP is indeed a privilege.
Sure, thank you. although I note that apparently you can come back if you go somewhere that is considered very far removed and an absolute exit, ie returning to the UK for a time? From what I read anecdotally, not firm evidence.
Can you use an ESTA repeatedly? Ie spend 90 days with your fiance (USC) whilst waiting for K1 approval, return home for a few weeks, then come back again?
