Do G-1 visa holders has uscis number?

G-1 visa holders do not have a USCIS number, as this designation is primarily for individuals representing foreign governments in international organizations. USCIS numbers are typically assigned to nonimmigrant visa holders who apply for certain benefits or statuses through USCIS. G-1 visa holders are usually not eligible for such benefits, as their status is linked to their government employment rather than individual Immigration processes.
