Current priority dates for F4 category (brothers/sisters of U.S. citizens) are: 01NOV2003 01MAY2003 01DEC2002 01MAY1997 15APR1993Most countries mainland China India Mexico Philippines So, if your brother is a citizen of Mexico, he will be eligible to adjust status in approximately 15 years; if he is a citizen of Kenya or Brazil - in 8.5 years. This is a long time to remain a student. Hopefully, some other avenues for adjusting his status will open up (marriage-based or employment-based green card). Meanwhile, he should think twice before crossing the border on a student visa: at entry, every non-immigrant must prove that he/she does not intend to immigrate to the U.S.; with an immigrant petition filed, it can be difficult, and an immigration inspector at the border can deny a non-immigrant entry despite the fact that he/she has a visa.
