我的情况是下个月要交485同时会申请AP。5月份要回国开会，AP可能还没法批下来。这
样子可不可以回国renew H1b visa回来？网上查了一下，各种答案都有。官方USCIS网
站上说
You may request travel authorization while your Form I-485 is pending. You
must file a request for advance parole authorization with USCIS and have
that request approved prior to travel or your Form I-485 will be considered
abandoned at the time of your departure from the United States.
是不是AP批准之前就不能离境？
