Why they don't increase altitude of ISS to overcome drag

    Experts -

    Why they don't increase altitude of ISS to overcome slight atmospheric drag it faces. Due to this, they need to make altitude corrections frequently to ISS.

    I want to know, why they can not put ISS in higher orbit where there is almost nil atmospheric drag (or may be altitude corrections are required once in 4-5 years....). Will it not be more fuel efficient approach ?
