问：如果移民局批准H-1B延期，对回美证有什么影响？
答：移民局解释说，对H-1B延期的批准具有终止回美证批准而将H-1B持有人归入H-1B非移
民身份类别的效果。原文为 "If the Service (USCIS) approves the alien's
application for an extension of nonimmigrant status, the decision granting
such an extension will have the effect of terminating the grant of parole and
admitting the alien in the relevant nonimmigrant classification.
is this true? I just got AP/EAD as well as H1B extended.
