What Is the DS-2019 Form?
The DS-2019 form is evidence that you have been sponsored by the International YMCA for your visa. It also indicates the dates between which you can work in the USA. You must obtain the DS-2019 before you apply for the J-1 visa. The DS-2019 is not valid without the J-1 Visa and the J-1 Visa is not valid without the DS-2019. You must keep the two together at all times.
