The Indian High Commission in Dhaka on Thursday issued guidelines on “air transport bubble” for travelling to India with immediate effect.
 
All Bangladeshi nationals can apply for all categories of visas (including dependents) except tourist visa, for travelling to India by air and water routes only.

“All existing visas except tourist visa and medical visa which remained suspended since March 12 are hereby restored for travel to India by air and water routes only,” a press release from the high commission read.
