It is not a problem... when u apply for it the officer downstairs (at the emmigration office near emmigr R/A) will say that u will need to get the approval from the captain. He sits in the first floor. U need to convince him that they are healthy and all... and the reason u r bringing them... he also checks ur company NOC letter and he signs it... I have done it 2-3 times

Once I was asked to present my degree certificate... So I had to go there once more...
