The Illegal Immigration Reform and Immigrant Responsibility Act of 1996 requires that all asylum applicants must apply within one-year of their last entry into the United States. However, there is an exception if the applicant can show that there are extraordinary circumstances directly related to the delay in filing.
Generally, maintaining valid status or humanitarian parole will be considered an extraordinary circumstance. If you were granted valid status or parole within one year or the date of your last arrival in the United States and you applied for asylum within a reasonable period of time of the expiration of your valid status or parole, generally this extraordinary circumstance would apply to you.
IILA and the other pro-bono attorneys aim to file within the one-year filing date but do not be alarmed if additional time is needed to prepare your asylum application. If you maintain humanitarian parole, the exception to the one-year filing date applies to you.
