Been to the US before, no problem. Flying from Prague to Frankfurt and from Frankfurt to New York tomorrow (2 separate flights) at 11am. My ESTA was not authorised and I found out just today, as I had no passport with me last week.
We are staying in New York till 1st of January then flying to Cuba. While applying I entered that its not transit. Should I try applying for ESTA as "transit"?
I have 2 passports, both are Czech. I used the new one VALID til 2029, The old one is full of old visas from mostly Africa and Eastern Asia.
I reapplied for new ESTA just now. I will fly to Frankfurt tomorrow for sure, is there any chance to obtain the ESTA on the airport? Or to receive ESTA in like 18h? I would call the embassy but unfortunately its holidays.
