lets say a dad and his kid came to the united states as tourists, they overstayed, and now are out of status. the kid is 17 years old and will be 18 by june 30. the kid's dad met a cuban girl who is a legal resident and wants to get married. assuming they get married on june 29th, will the kid be able to change his status along with his dad through marriage? and if so, does he have to get out of the country?
