Calbraz,

Thank you for sharing your polygraph experience. While I cannot predict with certainty how your next polygraph will go, I think it's likely that you will again be accused of deception and, quite possibly, using countermeasures.

If you tell your polygrapher that you visited this site and posted on this message board, then the likelihood of a countermeasure accusation will increase substantially.

While there is evidence of CBP using the polygraph to arbitrarily disqualify military reservists and guardsmen, I'm not aware of any institutional bias against veterans.
