I have completed Bachelors in 2002 and Masters in 2004, both in Electrical Engineering. On my PERM form ETA 9089, it has 'J.11 Education: Highest level achieved as required by the requested job opportunity = Bachelor's'. But details on J.13 to J.16 has information related to my Masters degree.

J.13 Year relevant education completed,
J.14 Institution where relevant education specified in question 11 was received
J.15 Address 1 of conferring institution
J.16 City, State/Province, Country, Postal code

I will be provide all the educational proof at the time of I140. Can I include a separate cover letter in I140 pack explaining this?
