父母B2簽證，女兒F1-> AOS，DS156填表一問請指教

女兒還在讀博，但身份已經由F1轉為AOS。
DS156表中第37項：
(1) Are Any of The Following Persons in The U.S.,
(2) Do They Have U.S. Legal Permanent Residence or U.S. Citizenship? Mark YES or NO and
(3) indicate that person's status in the U.S. (i.e., U.S. legal permanent resident, U.S. citizen, visiting, studying, working）。

我填： (1) daughter, (2) No.
想請教（3）該怎麽填？
是填： （3）AOS
還是填：（3） studying ？

謝謝指教！
