as an EU national you are NOT entitled to work in the US. You need an
employer to sponsor you for a job through a work visa. You need to
consult an immigration attorney particularly since you are looking for
non-skilled work. If you have an undergraduate (four year college)
degree, some employers will sponsor you for a "H-1" visa assuming they
have a job and the inclination to hire a non-American. If you do not
have an undergraduate degree it is considerably more difficult.
Anti-terrorism laws do not limit employment in non-sensitive jobs such
as airport baggage handlers or ramp agents (although they should!)
