Deadline for voting in Georgia primary

[LSUiLike]

What is the deadline for Georgia? Is it an open primary or do Georgia voters have to be Republican to vote in the Republican primary?

I'm pretty sure it's an open primary.

Deadline to register as a voter I'm not sure about.

Georgia is an open state. You must be registered to vote 30days before the election.
