Hello, I was wondering if I switch allegiance to a different Grand Company, will it reset my achievements?

I'm currently the top rank of my GC and acquired all that I wish to from the items, so was thinking about switching to another. However I would still like to get some of the rewards from the achievements long term (i.e. earn 500,000 seals etc.)

So I was wondering will my current amount of seals earned and other statistics stay registered, or will they reset upon my changing to another company?

Thanks
