What do employers have to do to hire foreign nationals as temporary workers?
To hire temporary workers, employers must file a petition with the US Citizenship and Immigration Services (USCIS). Employers seeking to hire certain categories of workers, H-1B (specialty occupations), H-2A (temporary agricultural workers) and H-2B (skilled and unskilled workers), must receive certification from the US Department of Labor prior to filing their petition with the USCIS. Once the employer has received notice from the USCIS that he or she can hire temporary workers, the foreign nationals then can file for nonimmigrant worker visas.
