I was working on a cruise ship, had travelled on a C1 D visa, I faced a back injury while working on the ship. My contract was shortened and I was sent back to India. The Passport has a PAROLED stamp with a pen written comment "to depart foreign", will I be able to travel back.
Not sure why you were paroled and not admitted given that you have a valid visa. Generally, you should be able to travel back to the USA given that you meet all other entry conditions. A parole stamp indicates that you were allowed into the territory of the USA without being admitted. In the eyes of the law, you were always at the border awaiting a decision on admission. Here you'll find a link which gives a more in-depth look into the legal meaning of parole in US immigration law.
