We report on recent advancement in the theory of light propagation in the Solar System aiming at sub-micro-arcsecond level of accuracy:

  1. (1) A solution for the light ray in 1.5PN approximation has been obtained in the field of N arbitrarily moving bodies of arbitrary shape, inner structure, oscillations, and rotational motion.

  2. (2) A solution for the light ray in 2PN approximation has been obtained in the field of one arbitrarily moving pointlike body.
