When “90 Day Fiancé” Season 6 premieres on Sunday night, viewers will be introduced to a cast of new couples and their loves stories. The TLC series will document the lives of Americans who fell in love with someone overseas and are ready to marry their foreign lover.

The couples will only have 90 days to get married to their significant other and secure their future together in the U.S. Failure to make it to the altar before their K-1 Visa expires means the foreigner will have to return to their country alone.

Meet the six couples that will be featured on “90 Day Fiancé” Season 6.
