My son recently started getting SSI. I heard there is a limit that he can save or he will lose it. What is limit? How do they check his account? Is it monthly or yearly average limit? If his check is due, can his account be just below limit or does it need to be enough below to have room for his check to be deposited without going over? Least question is most important. So difficult to teach saving for next months rent! I hope he can go off one day.
