Hi,

According to this page:

http://www.uscis.gov/graphics/formsf...ms/e-i-140.htm

electronic filing of I-140 is currently unavailable. Does anyone know when it may be possible to electronically file I-140 again?

And would there be any advantage in filing electronically rather than filing on paper? I would imagine that filing electronically may result in getting a response faster.
