Wwhen to disclose information about license?

I have a warning with stip on my license but I applied for the nursing jobs anyways even though I knew its going to be impossible to find a job. Today a hospital called me to set up an interview. But when do I disclose the information about my license? When they call me to set up an interview or should I go to the interview and then disclose the information to the nurse manager or whoever is interviewing me? A lady who called me didnt seems to be aware about my license situation. Should i call the lady tomorrow and let her know so she can decide whether or not she wants to go forward with my application?
Does the warning with stipulations prevent you from doing this job? Either way I think I would wait until they offer you the position. Then that way you know they like you and may want to work around it.

i feel as if the employment agency should to their checks on future employees. if the question arises be honest, but i do not think you necessarily have to call them back and tell them. good luck!
