hi! you can check the requirements for a US exam by visiting www.ptcentral.com. From there u can go to link that leads you to the Health Professions Bureau of the specific state where you want to take the exam. You can request for an application which you can use to apply for a tourist visa to sit for the said exam. I'm from the Philippines and I took the exam in Guam. Fortunately, i now have a license for Indiana.
