would i need to re applied to get the case seal again once its reopened?

To have it resealed it is just a motion. For the expungement there is a process. Unfortuanately this happens a lot with my immigration clients who have the luck of being arrested.

I see thank you. where do I file this motion? at the courthouse?

Yes with clekr in the division where the criminal case was filed.

okay i will do that. thank you so much for your input.

Sealing or expunging the record is not going to help you in successfully accomplishing your immigration goals.
