I am a graduate student in the US on an F1 visa (2017-2022). My Indian passport expires on 20th January 2019.
I need to travel to a conference held at Sweden on a Schegen visa. The dates are likely to be July 11th, 12th and 13th of 2018. Their rules require only 3 months of passport validity beyond the intended duration of stay. My intended duration is likely to be 2 or 3 days. So I am doing fine there.
However, I am not sure if it's okay to enter the United States again from Sweden in terms of passport validity. I am confused about the six-month rule. Subtracting six months from the expiry leads to 20th July 2018 as the last date of legal travel sort of. So, I am a bit worried if it would be fine to enter the United States on say 13th or 14th of July 2018 (roughly a week away from the six-month validity).
Looking for suggestions/help ASAP. Thanks!
