I'm from Czech Republic. I was working as a nurse and receptionist. ANy chance to find here some job?

I also am a bit confused about what you mean by "here".

The U.S. has been recruiting nurses from as far away as the Phillippines. Surely, a well-trained Czech nurse could find work too, but there are naturally a lot of immigration rules to work through first.

Where is 'here' exactly? If its London then theres thousands of jobs like that.
Monster,Hotjobs and Careerbuilder are some of the largest job boards where you could apply for jobs and upload your resume. Since,Craigslist allows free job postings,many companies post their job vacancies on this online classifieds website. You could also search for jobs in the USA using aggregators like Indeed and Simply Hired. Check this out for more details
