We consider the problem of projectively embedding pseudoconcave surfaces and the stability, under deformation of the complex structure of the algebra of meromorphic functions dened by a positively embedded divisor. We introduce weakened notions of embeddability for a smooth complex surface with strictly pseudoconcave boundary and a positively embedded, smooth divisor: \weak embeddability" and \almost embeddability." Almost embeddability of a strictly pseudoconcave surface is shown to be equivalent to embeddability of its boundary. This allows us to establish, in many interesting examples that the set of embeddable CR{structures on the boundary is closed in theC 1 {topology.
