its just another state-imposed burden you have to overcome - as long as you don't owe childsupport then you should get that cert in 4-6 weeks.
So just apply...
i applied for food vendor license in NYC , ( the personal ID ) to sell food from a permitted cart ..
they have asked me to give them ( NY sales tax certificate of authority ) , ID , SSN , Proof of address ) and the employee gave me a confirmation letter to attend 8 hours health class before getting the photo ID
when i arrived home i read the instructions again and found that i should apply for a (CHILD SUPPORT CERTIFICATION ) , the instructions said that i must apply for this certification , and i found some information which say that if i don't apply my food license may be cancelled , i know that i should call them tomorrow and ask about that , but i just wanna discuss this problem before call them , to make every thing clear to myself
