I think U are using pre-approved labor.
Edu issues are normally associated with them as U cannot tailor make Ur case.
The easiest way to get around is -- have the word 'equivalent' and allow combination of degree and work experience - for equivalency in the labor certification.
If you have them then I see U should not have any problems -- at the worst there might be an RFE and U can have a good evaluation done to make it equivalent to US 4 year degree programs.
U have so much experience and in addition U have a diploma -- with 3 + 2 years for masters --- I see no problems though.
Contact UnitedNations for more details -- he has a good way of evaluating regarding these issues.
Good luck
