父母B2延期，由於疫情, USCIS office關門，他們一直沒做biometrics。目前Application support center還是沒開門，不知道啥時候開。父母在8月底回國，我希望能在他們回國前做完biometrics。 想問: 如果 ASC 在他們回國前一直沒開門，那該怎麽辦？能不做biometrics就回國嗎？
-If they will leave US, they don't need to do the biometrcs. After they leave US, the B2 extension will be void, anyway. They need to keep the B2 extension receipt notice and bring it when they apply fro B2 visa or reenter US in the future.
