Abstract: Given a set $ E$ in $ \mathbb{C}^m$ and a point $ p\in E$, there is a unique smallest complex-analytic germ $ X_p$ containing $ E_p$, called the holomorphic closure of $ E_p$. We study the holomorphic closure of semialgebraic arc-symmetric sets. Our main application concerns CR-continuation of semialgebraic arc-analytic mappings: A mapping $ f:M\to \mathbb{C}^n$ on a connected real-analytic CR manifold which is semialgebraic arc-analytic and CR on a non-empty open subset of $ M$ is CR on the whole $ M$.
