Colliot-Thélène and Sansuc introduced universal torsors and descent methods to study weak approximation and the Hasse principle for rational points on projective varieties over number fields. We generalize these methods to the setting of strong approximation and the Hasse principle for integral points on affine varieties and apply them to two classes of varieties. This is joint work with Dasheng Wei.
