小白兔,能不能幫我看看我律師給我的回複?
If you have filed I-485, you may not be eligible to further receive F-1 benefit, such as CPT.  In practice, however, if the school still authorize you, you may get CPT authorization.  But if you need to sign new I-120, it involves issue of whether you do not state the true intention (In I-20 form, it requires you to attest non-immigrant intent).  
這麽說,我不能用CPT to work legally,既然我遞交了485。
用EAD是唯一的出路了? 除非在學校老老實實呆著,還能繼續F1?
