8老師好，2012年姐姐（美國公民）為我申請F4遞交了I-130表格，現在仍然在等待中。目前，她搬家了，我也從中國來到了加拿大（持PR），我希望您幫我確認的是：1.我們怎麽更改地址，在線https://egov.uscis.gov/coa/displayCOAForm.do？
2. 我姐的美國地址和我的居住地址都要改嗎？
-Yes. If your sister filed the I-130 online, she can go to her online USCIS account to change both your address and her address in I-130. If she filed I-130 by paper, She can call USCIS at 1-800-375-5283 to ask USCIS to change her address and your address for the I-130. Click "USCIS online account" at this link:
How to Change Your Address | USCIS
If USCIS has forwarded the approved I-130 to National Visa Center (NVC), your sister also needs to inform NVC for the address change using Public Inquiry Form. See:
Public Inquiry Form (state.gov)
If your sister has had the NVC account already, she can also update the address following the instruction in this link (See "Updating your contact information" part at the link):
謝謝，盼複，祝秋安！
