How long does a US B2 visa take to be issued once applied for? (I'm in New Zealand)?

Answer 1

Well, if you are a New Zealander, you could enter under the Visa Waiver program. But if you feel you need an actual visa in your passport, it currently takes only 3 days to get an interview appointment in Auckland, according to travel.state.gov. You can check out the consular website at

Answer 2

Two to three months from the time of appointment until the delivery of the passport with visa.
