When people seek asylum in the U.S., they make mistakes that could be avoided. A mistake in the application process can result in the denial of their asylum claim and change the immigrant's fate. To the extent that such mistakes are avoided, the likelihood that the asylum application will be granted increases.Most asylum seekers must file their applications with U.S. Citizenship and Immigration Services (USCIS) within 12 months of their most recent entry into the U.S., except when extraordinary or changed circumstances related to the delay in the application arise, so it must be determined whether there is a valid reason to file an application outside of the required time frame.The book presents aspects to take into account in order to avoid losing the opportunity to obtain asylum in the United States.A series of typologies of people who fail to obtain asylum are presented, as well as an opinion survey with jurists who explain why applications are sometimes rejected.
