There is no special visa for clinical skills exam. You have to apply for B1/B2 visitor’s visa. Visa officer believe that every applicant for non-immigrant visa is a potential immigrant. Your task to acquire the visa is to prove that you are not a potential immigrant. You do this by showing
Strong ties to your home country. This will be in the form of fixed assets in your home country (i.e. property) and employment commitments (take a letter from you employer confirming your job and pay.
Financial standing: visa officer likes to see that you have enough finances at home that can support your visit and stay during you visit to United States. You can show this in the form of your recent payslips if you are currently employed and your bank statements showing transactions for last 3 to 6 months.
People who are still in the medical school who have financial backing from their parents stands a very good chance to get a visa because they have a very strong reason to come back to their home country to complete there graduation after passing the exam.
Marriage: people who are married stand a better chance than people who are not married.

There is some debate in the fmg’s about disclosing at the time of interview if they are going for CS or just for a visit. I don’t think it is a good idea not to disclose anything. I know lots of fmg's applying from UK feels that they don’t get any problem when they have applied for visit visa for tourism rather than for CS purpose.
