USCIS Policy Memorandum PM-602-0045 (August 17, 2011)

U.S. Citizenship and Immigration Services (USCIS) issued this policy memo to ensure that USCIS adjudicates Form I-539 applications for changes to and extensions of B-2 visitor status "uniformly and consistently with the manner in which" the Department of State [DOS] issues B-2 visas to cohabitating nonimmigrant partners and other household members of principal nonimmigrants when the household member cannot obtain derivative status as a dependent [see 9 FAM 41.31 N14.4].

The policy memo updates the USCIS Adjudicator's Field Manual (AFM) to define "household member" for this purpose as "an alien who regularly resides in the same dwelling as the principal nonimmigrant and with whom the principal nonimmigrant maintains the type of relationship and care as one normally would expect between nuclear family members."
