It's a common misconception that a nonimmigrant status somehow leads to a green card or limits the green card options in any way. There is no connection between the two. So someone in IEP "status" could pursue a green card but because IEP is not considered an admission, he or she would have to go the immigrant visa route through a US Consulate abroad rather than the adjustment of status route through USCIS.
