Some WTO members have referred to the
regulations used to grant work permits in their GATS
schedules of commitments, even though specific
numbers of work permits have not been subjected to
multilateral trade negotiations. Thus, statistics on the
number and type of work permits granted and currently
valid (e.g., by duration and occupation) would be of
great interest to trade negotiators.
24. Some countries may be able to obtain relevant
information from government-run social security
systems and national health insurance schemes, although
they normally only cover resident foreigners who are
economically active. Statistics on arrivals and departures
monitored by immigration or tourism authorities may
provide information about foreign nationals concerning
their origin/destination, length of stay, purpose of visit
etc.
