How can I repetition my son from the philippines to come here in the U.S from single to married status?

if you are an American citizen, you don't need to repetition him, as his status automatically changes from F1 to F3, unless he married before you became a US citizen. in that case, you would simply file a new petition. If you aren't an American citizen, your petition became invalid after he married. in that case, you would have to become a citizen first and then file the petition.
