I have a question regarding social security and/or other federal benefits, where do I go for assistance?

The Social Security Administration (SSA) has consolidated its overseas operations and will no longer be offering social security assistance through the United States Embassy or Consulates in Canada. Individuals residing in Canada who require social security services or have questions about SSA benefits must contact their nearest SSA field office in the United States.
