Will my Retirement Visa be Terminated when renewing passport in USA?

I have annually renewed my Thai retirement Visa and Re-entry permit for seven years. When renewing this past December, immigration granted my renewal only thru August 19 because August 19 is when my US Passport will expire.
I am considering a trip to the US in MAY and, while there, applying to renew my passport.
Does anyone know: if I renew my passport in the US in May, will the new passport include existing Visa stamps from the current passport? or is it probable that my new passport will have all blank pages and no existing Visa to return to Thailand with? Do they return the passport that you are renewing or give you a brand new one or both? i realize this is more of a passport renewal question, but hoping some people can offer knowledge based on their experience. ( FYI- I realize I can visit US embassy’s in Thailand to renew my passport but would rather accomplish the task in the USA) Thank You!
