My daughter Age 16 1/2 is now married to an Egyptian age 20 they are now married and known each other for 2 years and have met 2 times in person. She is now trying to get him to the USA. Our family income is over 100,000 dollars/year, she is still a student. My question is can I co sponsor and does she have to be 18 before she can request. They married in Egypt last month.
