An applicant who wishes to file for benefits under the agreement with Luxembourg must
complete form SSA-2490-BK (Application for Benefits under a U.S. International Social
Security Agreement). This is true whether the applicant is filing for benefits only
from the United States, only from Luxembourg, or from both countries.
NOTE: Accept applications for Luxembourg benefits up to one year in advance of the entitlement
Accept applications for U.S benefits up to four months in advance of the entitlement
Follow GN 00204.007C when an application for U.S. benefits is filed more than four months in advance of
the entitlement date.
