Thanks!

Consider, for example, the following scenario. A person from Country A (such as Canada) takes a vacation in Country B (such as Mexico). In this example, while on vacation, the person from Country A (Canada) brings his or her laptop computer to country B (Mexico) and performs some work tasks on the computer while vacationing. This kind of scenario happens frequently, in many varying countries, and is not usually considered to violate the rules and regulations governing visitors. In practice, it appears to be widely tolerated.

And thus it is typically not considered to be problematic, as long as the work is being sent back electronically to the original Country A, and an organization within Country A (and not Country B) is paying for the work to be done.

If the work however, involves interacting with persons in Country B (such as potential clients) then there is a chance the person may be considered to be working out of status in Country B, and in violation of the rules and regulations governing visitor status.
