So ive been reading the post and i havent managed to find the one that suits me

so i recently just got fired and ive been searching but im gradually getting more and more nervous... i am an american citizen without a unbefristed work permit and i would like to know, can i got to a work agency such as manpower so they can find me a job or is that something for only eu and people with unbefristed?

Thank in advance hope its a positive answer otherwise gotta find a job fast!!
