If you're completely checked out from family members and friends and acquaintances around you and you're a complete loner, then yes, you'll be having a hard time finding someone to JS your beneficiary. The financial repercussions of signing affidavit of support docs, for a beneficiary who IF they become a public charge after getting their greencard -- are probably way less than getting someone an additional credit card under your line of credit. At least the bank will go after you if the bills are unpaid. Here the government just doesn't give a rats behind if a beneficiary later becomes a public charge. They were seriously going to start enforcing Aos during the previous administration but then elections happened.
