Once you receive the survey link, complete it and receive credit immediately or whenever it is done and this varies with different paid survey programs.

The other best way to find the genuineness of a paid survey is to actually join them and see whether how it works. This will work out only if it is free to join else it is not advisable to do so. After joining the trial paid survey sites, just finish off the first survey and see whether they do indeed credit your account for the completed surveys or not, if they don't then it is time to say goodbye to that particular paid surveys program.
