Which makes zero sense, because this has always been the case. When I moved here twenty years ago on a K-1 visa, my partner had to sign an affidavit of support saying that regardless of any contributions I made (paying taxes, social security, etc.), that any "public charge" would be directly billable to her through the IRS. -And- she had to demonstrate ability to be able to meet that obligation. That financial sponsorship applies for the first ten years of the immigrant's residency.

Whatever updated guidance and training is needed here is one of two things, 1) something that could be handled in a matter of days or weeks, or 2) "We have no idea how long this could take so we're suspending it indefinitely" (which is what they're doing), and the "updated guidance and training" is a smokescreen for Steven Miller's agenda of becoming a closed nation.
