If he was in the US unlawfully for more than 1 year, he is barred from reentry for 10 years unless he can get a waiver on the showing of extreme hardship to a US citizen spouse, which is fairly difficult to do in most cases. If he has only been out of the US for 3.5 years, it looks like he may be barred from entry to the US for another 6.5 years.
