I'm in the middle of applying for public trust clearance

But I got a petty larceny incident six year ago. It is one single isolated case under very stressful situation. How much chance do you think I get to obtain this contractor position?

A public trust position does not involve getting a clearance, but rather a determination is made as to whether you are suitable for the position. If all you have is a petty theft charge and nothing else since then you should be okay. (except for law enforcement positions, where it might be an issue)

Thank you for getting back to me. I heard DHS is very aggressive and strict. Once I got denied, it will be better to wait for two years to re-apply. Is it true? I am trying to estimate the risk of getting a denial in my background investigation, it will look bad in the long term. Thank you very much!
