I have about R-19 insulation in attic. I want to add R-30 more. R-30
batts in HomeDepot have paper vaopr barrier. Should I remove it before
adding R-30 batts over existing batss to prevent double barrier or I
can put them as is?

Just put a couple slashes in it to give any moisture a route out. Odds are
your installation won't be perfect enough to matter anyhow.
