Can anyone do this? What if I don't live in the United States?

Most paid survey opportunities require that you are at least 18 years of age, but other than that there are no specific requirements. You do not need any special qualifications or skills.

Survey opportunities are NOT limited to U.S. residents - everyone is welcome.

Some surveys are very specific, and not everyone will "qualify" for every survey. For example, a particular survey might only be open to women between the ages of 25-45 who live in the US. Another survey might only be open to single men who use cologne, etc.

Of course, a lot of surveys are very general and just about anyone can take them. In the end, there are usually plenty of survey opportunities for just about everyone.
