父母B2入境 很快遞交了綠卡申請（130，485）。 遞交沒多久就發現不適應這裏生活不適合久居，決定撤回綠卡。請問：
1. 撤回綠卡後是否自動回到B2身份？
-The B2 status is still valid during I-485 pending unless the I-94 expires.
2. 是否I94過期前出境就可以？
-Correct.
3. 撤回綠卡後是否會影響以後的B2申請？
-It should not affect the B2 visa application. USCIS will send them the I-485 withdrawal notice after the I-485 withdrawal request is approved, i.e., the confirmation letter-officially closed your parents I-485 application.
?Your parents should bring the I-485 withdrawal approval notice when they are interviewed for the new B2 visa application or enter US using B2 visa in case the officer asks the immigrant intent questions.
4. 如果B2簽證還有幾年有效期， 撤回綠卡是否會影響以後入境？
-It should be fine. See above.
