Answer:
d. work permit
Step-by-step explanation:
The work permit is also referred to as the
Employment Authorization Document or EAD. A
work permit has the same design as a driver's
license. It is issued by US Citizenship and
Immigration Services (USCIS).
Foreigners coming into the US need to obtain a
work permit to enable them to seek employment.
The work permit card is presented to potential
employers as proof that a person is duly
authorized to work in the USA.
