Seminar on Algebra, Geometry and Physics Veech groups of square-tiled surfaces are a natural source
of non-congruence subgroups of PSL(2,Z). Following work of G.Weitze-Schmitthüsen and C.Weiss we show that they are 'totally non-congruence'.
However, due to their geometric origin Veech groups come with a modular embedding and we discuss consequences for modular forms for these groups.
