sorry to bother everyone.

i am a F1 PhD student.

i want to apply NIW.

however, i found a problem about the I-140 part 6.

part 6 is about basic information about the proposed employment.

since i am F1 student. i am not in work. i get fellowship from University and not work as TA/RA.

thus, hwo to fill in this part? can i leave the part 6 of I-140 as blank?

thank you very much.
