Note: This paper computes these scores based on the classification summarized in the WTO document (JOB[03]/195), which describes frequently-used categories of natural persons included under mode 4 in the horizontal section of members' schedules of specific commitments. The four main categories are intracorporate transferees (ICT), business visitors (BV) and service salespersons (SS), contractual service suppliers (CSS) and other categories. CSS includes employees of juridical persons and independent professionals. Other categories contain graduate trainees and spouses and partners of ICT.
