As a US citizen applying for a married son or daughter, your case falls under the F-3 category which currently has a backlog date of December 15, 2007 for the month of March 2020 for natives of all countries except for Mexico and the Philippines which must wait longer. Assuming that you are not born in Mexico or the Philippines, the waiting time is approximately 12 years at present.
