The applicant's life or freedom shall be found to be threatened if it is more likely than not that he would be persecuted on account of race, religion, nationality, membership in a particular social group, or political opinion.

If the applicant is determined to have suffered persecution in the past such that his life or freedom was threatened in the proposed country of removal on account of race, religion, nationality, membership in a particular social group, or political opinion, it shall be presumed that his or her life or freedom would be threatened on return to that country unless a preponderance of the evidence establishes that conditions in the country have changed to such an extent that it is no longer more likely than not that the applicant would be so persecuted there.

In evaluating whether the applicant has sustained the burden of proving that his life or freedom would be threatened in a particular country on account of race, religion, nationality, membership in a particular social group, or political opinion, the officer or judge hearing the case shall not require the applicant to provide evidence that he would be singled out individually for such persecution if:

1. The applicant establishes that there is a pattern or practice in the country of proposed removal of persecution of a group of persons similarly situated to the applicant on account of race, religion, nationality, membership in a particular social group, or political opinion; and

2. The applicant establishes his own inclusion in and identification with such group of persons such that it is more likely than not that his life or freedom would be threatened upon return.
