The Ninth Circuit has determined that a stowaway who is granted asylum in asylum-only proceedings does not lose his status as a stowaway, but merely gains the additional status of an asylee. As such, if the asylee is convicted of an aggravated felony, it is proper to reopen the asylum-only proceedings. In such circumstances, the asylee cannot apply for adjustment of status with the Immigration Judge, but can apply with U.S. Citizenship and Immigration Services.
