請問：（一）他搬到加州去，就不會被遣返嗎
-No unless he is caught by police (e.g. he makes any crime). But the consequence of unlawful presence is serious, e.g. he can not get the green card or legal status anymore unless he marries a US citizen.
（聽說加州接受非法移民？哪裏能查到正式的說法）？
-I have never heard it.
（二）如果他黑下來了，我作為他J1的sponsor，要承擔什麽後果嗎（我自己是綠卡）？謝謝指教（能給出有關法規鏈接最好）。
-No. By the way, you are not his J-1 sponsor, and his J-1 sponsor is your employer.
（他是J1 Researcher，國際辦公室說最多隻能在美國待一年，不能延、不能轉；像他這種，能找個community college之類的轉成 J1 student嗎？謝謝。）
-No. J-1 holder can not change status within US unless he gets J-1 waiver, but he may go to China to get the F-1 visa to come back to study without J-1 waiver.
