Many countries are happy to welcome visitors, but want to be sure they don’t plan on overstaying their visit. Peru, Brazil, and New Zealand, among other countries, require proof of onward travel before they will allow you to enter. If you have a roundtrip airline ticket, that’s usually all the proof you need. However, this requirement sometimes poses a problem for travelers who don’t have firm travel plans. For those travelers, showing an inexpensive bus or train ticket to another country is usually sufficient. An onward air ticket, even if refundable, is also usually accepted. If entering a country with an onward ticket requirement, be prepared to answer questions about when you plan on leaving and have your onward travel documents ready to share.
