"We’ve seen varying timelines, but generally the passport renewal process can take anywhere from four to 18 weeks via mail, with in-person meetings even harder to come by,” says John Spence, USA president for luxury tour operator Scott Dunn. The government’s passport renewal website says travelers should be prepared to wait up to 18 weeks from the day their mailed-in passport reaches a processing facility.

Any travelers who can provide proof of necessary urgent travel, such as life-or-death emergencies, or can show that their trip is within 72 hours, though, are given the chance to score an in-person appointment, Spence says. “However, we wouldn’t count on this unless it’s a last resort,” he adds.

If you are able to get an in-person appointment at one of the government’s 26 passport agencies or centers in the country, a passport agent will review your application and potentially issue a passport on the spot, if you’re eligible for one. Or, the agent may ask you to return at a specific time to receive it, depending on the agency, their workload, and the date of anticipated travel.
