I am looking at the travel arrangements for flights from Bangkok to St Martens as the individual will be working in the British Virgin Islands. She has her visa to work and will be requiring a flight at the end of September.
The most economical way of getting her to St Martens is via Miami but because of the visa restrictions this is not an option as she has not applied for a US visa. The next option is via either Amsterdam or London. The latter is an option as she will have a BV visa. Would she need a visa just to transfer through Amsterdam?
