I am not from Saudi Arabia but you may print the FBI fingerprint form from fbi . Gov and take it to a police station and ask them if they can take your fingerprints on the FBI form. Or check on the Internet if you can find any fingerprinting agencies that can take your fingerprints for a fee. Personally, there is an international service at the main police administration in rabat, where I took my fingerprints. I do not advise you you take them yourself as there is a strong probability that might get refused and then get stuck for months.
