We apply the supplementation trick Phys. Lett. B 381 (1996) 105 to the Green-Schwarz superstring. For type IIB theory both first and second class constraints are covariantly separated and then arranged into irreducible sets in the initial formulation. For N = 1 Green-Schwarz superstring we propose a modified action which is equivalent to the initial one. Fermionic first and second class constraints are covariantly separated, the first class constraints (1CC) turn out to be irreducible. We discuss also equations of motion in the covariant gauge for κ-symmetry. For type IIA theory the same modification leads to formulation with irreducible second class constraints.
