Difference of UK payroll and US payroll

Payroll is determined by the passport you hold. If you hold more than one passport you may be able to choose which payroll your paid on.

New employees are placed on the payroll designated for the employee’s primary country of citizenship acceptable to the Company. In order to be placed on a different payroll, an individual must have substantial educational and/or work experience in the country from which recruited, or another country which is being requested by the employee. Such evaluation is based on the facts and circumstances of each case; this includes the prospective employee’s residence status in the country being requested as a reference for payroll assignment and, in the case of holding two passports, the passport used to obtain employment in a third country prior to joining Saudi Aramco.
