Here's a bit of background about myself
I'm an Indian national, who is in working in the US. My wife is Bengali (Indian), her grandparents were from Bangladesh.
The next time we travel back to India on vacation, we were planning to first goto Bangladesh, visit for a couple of days. Then take the train to Kolkata (West Bengal), spend a few days with my wife's family.
I wanted to know if it's possible for me to take the Maitree Express from Dhaka to Kolkata. I ask specifically because the process didn't seem too clear to me, here is the documentation that I found for the Bangladeshi side. It mentions that valid documents are needed, what those documents would be isn't mentioned.
I would ordinarily have assumed that just my Indian passport would suffice but it seems like the visa should specifically mention the mode of entering the country. Another confusion is how I would request such an endorsement whilst applying for a visa. In my case I want to enter Bangladesh by air but leave by train.
In your answers, if you can share your experiences with this trip or a similar trip where the mode of entrance is different than the exit; that would be very helpful.
