My father recently renewed his B2 Tourist Visa - and was given the 10-YR Multiple entry visa. He is currently visiting USA and his current I 94 expires in end of May 2019. Due to some medical issues - we were contemplating about requesting a 2 to 3 months extension for his stay - if possible. Would you necessarily have to provide an evidence in the form of a return ticket (about 3 months hence from end of May 2019) - to prove that he indeed intends to go back
As far as I know they often do require a return ticket. FAQ in detail...
