diffrent dates between J1 visa and DS 2019

[mohamedfayez12345]

My interview was on 11th of may and although visa is approved it now shows administrative processing. the problem is that the start date on the DS form is 1st of may which means i should enter before 30th of may which is highly unlikely and so i requested a new DS 2019 form. My question is if J1 visa is issued can i use it or will i need a new one given that i have a new DS 2019 form
Thanks
