This is the complete immigration inspection of airport passengers before departing a foreign country. These immigrants do not need another inspection when they arrive in the United States (however, nonimmigrant noncitizens must submit Form I-94).
The legislature occasionally skips outline levels.
For example:
(3) A person may apply [...]
(4)(a) A person petitioning for relief [...]
In this example, (3), (4),
and (4)(a) are all outline levels, but
(4) was
omitted by its authors. It's only implied. This presents an
interesting challenge when laying out the text. We've
decided to display a blank section with this note, in order
to aide readability.
