My wife had 3 years PCL and 2 years bachelors degree from Nepal. We used CES from cgfns. Also we didn't use her 2 years bachelors degree. We used PCL degree for credential evaluation with CGFNS. English proficiency requirement is the requirement of board of nursing so check with Montana board of nurisng for english proficiency. SSN is not required by CGFNS but the board may require it.
