India to US travel via 3rd country other than Mexico

We have applied for an NIE but still haven’t gotten a reply back. We are looking at other options for travel. We are planning to travel at least by the end of the month. What countries other than Mexico are allowing Indian citizens without a visa? We have valid H1/H4 visas.

You can go via Dubai. No visa needed for 14 days visit with a valid US visa.

Do you need an entry permit/visa to enter the UAE? - The Official Portal of the UAE Government.

Hi, I have a valid H1B visa and currently in India. Planning to travel to Mexico to stay there for 14 days and return to US from there. Is traveling to Mexico from India transiting through US allowed ? Was talking to United airlines and the agent said it is not allowed and I will be dined boarding the flight if booked. The itinerary would be Hyderabad- New Delhi - Newark - Cancun. Thanks.

Only C-1 & D-1 are allowed for transit via the US.
