媽媽目前是H4，女兒是公民今年8月滿21歲後準備為媽媽申請綠卡，但爸爸已被裁員，媽媽必須轉B2才能留到8月，所以先file i539轉B2，5月到8月用轉B簽證cover status， 8月再file i130有沒有問題？等i130 和i485都file之後再withdraw i539，這樣對嗎？謝謝！
-Fine. She does not need to withdraw the B2 application. Her I-485 will not be affected no matter whether the B2 application is denied or approved later.
You need to make sure your kid has enough income (e.g., she has a job now) to support you for the green card application. If she has no enoguh income, you need to find a joint sponsor.
