Czech Jobs - most Czech job boards are only in Czech language.
Only a few support English, which is a reflection of the fact
that most employers expect job applicants to speak Czech. International
experience is not typically viewed by Czech employers as very benefitial.
Foreign applicants do require Czech working visa. More details
regarding immigration and work permit requirements
can be provided by the Czech embassy or consulate in your country.
US Jobs - Some US based job boards and services cater to international
job applicants. Foreign job applicants require working visa,
before they can legally start working in the US. This step has to be
sponsored by a prospect employer. Detailed information regarding
immigration to the US is provided by the US
Immigration and Naturalization
Service (INS) or US embassy in your country.
