Even if you have the 5 years you still need to show the 3 as equivalent to a US bachelor's degree.
Sheila,
His RFE says that "The service holds that a 3 yr BS from an indian university + 2 yr MS from an indian university is equivalent to a US BS degree ". it means USCIS is position is on this to consider it as equivalent to US Bachelor. So if he shows 5 years progressive experience should there be any problem?
