We show that any integral second cohomology class of a closed manifold Xn, n ≥ 4, admits, as a Poincaré dual, a submanifold N such that X ∖ N has a handle decomposition with no handles of index bigger than (n + 1)∕2. In particular, if X is an almost complex manifold of dimension at least 6, the complement can be given a structure of a Stein manifold.
Keywords: taut submanifolds, almost complex manifolds, symplectic manifolds, almost symplectic manifolds, Stein manifolds
