If the claimant contacts a Luxembourg agency to apply for both U.S. and Luxembourg
benefits, the agency obtains the required Luxembourg application form. The form asks
for an indication of work in another country. If the claimant indicates work in the
U.S., the Luxembourg agency notifies OIO using a liaison form.
The Luxembourg agency prepares and forwards the following material to OIO:
Liaison form LUX/USA 3, certifying the filing date and requesting a U.S. coverage
record and/or entitlement data if it is needed.
Luxembourg coverage record.
Available medical evidence if the claim is for disability benefits.
