ED 2

I was wondering if I should apply to the college for ED2. Does it have any advantage over regular for financial aid (I’m an international student who isnt from a very affluent family so I’m looking forward to a need-based scholarship). Also, I have currently applied for EA to Howard University. Will applying for UC ED2 cancel out my EA automatically even if I’m still in the waiting stage?

The college I was referring to was Union College btw
