A school cannot change someone’s aid based on what ifs.
If it’s not affordable currently, then assume it will stay the same.
If something changes you can appeal.
But maybe my dad will lose his job is not basis for change.
You should be applying to schools that will be affordable, whether or not your dad loses his job. Therefore it may not be schools you desire. But that’s secondary to affordability.
Good luck.
Ps - CSS schools like Emory will use the CSS form. FAFSA is required but it won’t be the basis of your aid determination.
