We study nearly holomorphic Siegel Eisenstein series of general levels and characters on , the Siegel upper half space of degree . We prove that the Fourier coefficients of these Eisenstein series (once suitably normalized) lie in the ring of integers of for all sufficiently large primes . We also prove that the pullbacks of these Eisenstein series to are cuspidal under certain assumptions.
