(Sec. 101) Amends Immigration and Nationality Act (INA) provisions concerning asylum to: (1) authorize the Secretary of Homeland Security, in addition to the Attorney General, to grant asylum (retroactive to March 1, 2003); (2) require asylum applicants to prove that race, religion, nationality, membership in a particular social group, or political opinion was or will be (if removed) the central reason for their persecution; and (3) provide that an applicant's testimony may be sufficient to sustain this burden of proof only if the trier of fact determines that it is credible, persuasive, and fact-specific. Requires corroborating evidence where requested by the trier of fact unless the applicant does not have the evidence and cannot reasonably obtain it without departing the United States. States that the inability to obtain corroborating evidence does not excuse the applicant from meeting his or her burden of proof. https://www.congress.gov/bill/109th-congress/house-bill/418
