If you present a good case, you should get your raise the first time but if you feel mentioning the other job offer is advantageous then by all means, do it. Realize though, not all employers like that approach and they may just tell you to take the other job so be prepared for that. Once you play that Ace, there's no bringing it back.If that doesn't work? I feel that going back in a month later to try and get more will be ineffective.
