Refugees looking to enter the United States will have to adhere to new visa guidelines set forth by the Trump administration. Visas already approved will not be revoked, however, new applicants from Syria, Sudan, Somalia, Libya, Iran and Yemen must prove a relationship with a parent, spouse, child, adult son or daughter, son-in-law, daughter-in-law or sibling already in the United States to be eligible. Grandparents, grandchildren, aunts, uncles, nieces, nephews, cousins, brothers-in-law and sisters-in-law, fiancees or other extended family members are not considered to be close relationships. The new rules take effect at 8 p.m. Eastern Daylight Time on Thursday, according to the cable, which was obtained by AP. The new rules come after the Supreme Court's decision to reinstate parts of President Trump's oft-criticized travel ban.
