我現在是F1留學簽證，三年之後簽證到期，（加上opt的時間，我不確定在綠卡發下來之前我的身份是否一直有效）我現在想申請F2B移民，我的i120表格裏的申請大使館應該填國內還是國外呀，還是國內外都填（不確定到時候需不需要回國重新辦簽證）。如果我一直不離開美國我還需不需要重新辦簽證？我可以在美國境內拿到綠卡麽？
At which USCIS office will the beneficiary apply for adjustment of status to lawful permanent resident?
You should only answer this question if the beneficiary is in the United States and will apply for adjustment of status at a USCIS office in the United States.
If the beneficiary will apply for adjustment of status to lawful permanent resident inside the United States, you must provide the location of the USCIS office where the beneficiary will apply for an immigrant visa.
At which U.S. Embassy or Consulate location will the beneficiary apply for an immigrant visa?
Choosing a U.S. Embassy or U.S. Consulate outside of the country of the beneficiary's last residence does not guarantee that it will accept the beneficiary's case for processing. In these situations, the designated U.S. Embassy or U.S. Consulate has discretion over whether or not to accept the beneficiary's case.
