  In this paper we study the structure of complex points of codimension 2 real
submanifolds in complex $n$ dimensional manifolds. We show that the local
structure of a complex point up to isotopy only depends on their type (either
elliptic or hyperbolic). We also show that any such submanifold can be smoothly
isotoped into a submanifold that has 2-strictly pseudoconvex neighborhood
basis.
