It asks what the highest level of education the sponsor has completed in this form. I (the sponsor) was unofficially homeschooled as a kid. Meaning I was taught at home, but my parents did not notify the school board, so there's no official record of my homeschooling. Should I leave of levels of education unchecked in this section? Should I attach a note explaining? And will this impact the spousal sponsorship, even if I can prove that I have the means to support my wife?
