“Proration” means that you receive a fraction of your SSI benefit (Federal benefit plus any federally administered State supplement) that would otherwise be due for the month.
Proration happens only in the first month you re-attain eligibility after a period of ineligibility. The fraction is based on the date you first re-attain all factors of eligibility for SSI. Both Federal SSI and federally administered State supplementary payments are subject to proration.
Factors that can cause proration are:
No longer being a resident of a public institution;
Being present in the U.S. after an absence;
Regaining residency status in the U.S.;
Again meeting the definition of citizen, alien lawfully admitted to U.S., or alien permanently residing in the U.S. under color of law; and
Compliance to file for other benefits.
The proration formula is as follows:
Take the benefit that you would otherwise be due for the month;
Multiply the amount in (A) by the number of days in the month from (and including) the date you meet all factors of eligibility through the end of the month; and
Divide the amount in (B) by the total number of days in the month.
