Like the Operation Instructions
(OIs), Interpretations were created to supplement and clarify
the provisions of the statute and regulations as interpreted by
the courts. These materials usually are not included in the regulations
because they deal generally with procedural matters and do not
deal directly with application and benefit requirements. They
are still a useful tool to help you understand how the DHS Bureaus performs
their different immigration services and enforcement functions. Users of the Operation Instructions and
Interpretations should always consult the relevant regulations
and manuals in conjunction with these materials. As the DHS Bureaus have
grown, the trend has been towards inclusion of more materials
in the regulations and field manuals, and the Operations Instructions and Interpretations have been
updated less frequently.
