i am indian citizen and have work visa for brazil, my visa is getting expired and i already have file my extension, and i have letter from brazil gov saying - while gov investigate and approve my visa extension i am eligible to stay in brazil for 90 days" at this moment can i go to india and come back? while coming back brazil authority will surely allow me to enter into brazil, but the confusion is will Indian authority allow me to leave india if i show them the letter from brazil gov? can i ask somebody in india to confirm this for me before i leave brazil? from where one can confirm this thing in india ? any immegration office?
