My H1-B(I-129 petition) is approved, as COS , in this cycle and will be valid from 01-Oct-2021 .
My F1-visa & EAD is valid till next year (May-2023 & Jul-2022 respectively).
In this scenario, can I travel to India around July-August and return before 30 Sep 2021 ?
Is there any challenge in this and what all things should I be careful about ?
Can the CBP officer deny entry on F1-visa and ask to enter after Oct on stamped H1B Visa ?
