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

    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 ?
