user: Good evening. May you comment me about renewal for hazmat endorsement, please?[NEWLINE]agent: Do you want to renew your hazardous materials endorsement?[NEWLINE]user: No, this in not about that.[NEWLINE][BOUNDARY][NEWLINE]agent: Are you searching for information about your background check?[NEWLINE]user: No, neither that. I have some information about that regard.[NEWLINE][BOUNDARY][NEWLINE]agent: Is then your inquiry aimed to know how to give your fingerprints on the background check?[NEWLINE]user: Not at all.I already told you that i have some information about that process.[NEWLINE][BOUNDARY][NEWLINE]agent: Sorry, is just the standard procedure to do this series of questions. So please, bear with me. Maybe are you interested into knowing how much time will be invested on your checks?[NEWLINE]user: In fact, i think i don't have information about that topic, so i guees i should say yes to that.[NEWLINE]agent: Good. You must know about this regard, background checks can take up to 30 days or more to be complete.[NEWLINE]user: That's quite a lot of days. What happens if my endorsement expires before you're done with my checks?[NEWLINE]agent: In that case, you'll have to wait until all the background check process is completed before your endorsement can be restored and you re-qualified by both the TSA and the DMV.[NEWLINE][BOUNDARY][NEWLINE]user: All this process can be done by mail if i want?
