There are many other churches that list themselves under Catholic Churches. The list below are not in union with the Holy See and the Roman Catholic Bishop of the Diocese of Las Vegas. Thus, these Churches are in schism. Attending Sunday Mass at any of these establishments does not fulfill the obligation to attend Mass.

First of all,

They do not recommend it, but clearly they do not forbid it and it IS possible to fulfill the Sunday and holy day obligation at chapels of SSPX.
The Rev. Msgr. Camille Perl, the former Secretary, second in charge of the PCED, responded to (a) query personally, in a letter dated 20 March, 2009, by stating: "Our response is that it is possible to fulfill the Sunday and holy day obligation by assisting at Masses of priests of the Society of St. Pius X, but until such time as their situation is regularized in the Church, even though they are part of the Church, we cannot recommend your doing so."
During the "Year of Mercy," (2016) Pope Francis has extended to SSPX the faculties for hearing Confession and granting Absolution, even though they are not fully "regularized." One does not extend this jurisdiction to a schismatic church.
