Are you thinking of study abroad in winter or spring of 2022? If so, please note that the US State Department has announced very lengthy processing times for passport issuance. If you don’t yet have a passport, or will need to renew your passport before traveling, you should take care of that this summer and not wait until the fall!
Note that your passport must be valid for 6 months after the date you will return home from your study abroad experience. So, for most students going abroad in Spring 2022, that means that passports should be valid until the end of November or December 2022.
