我写信问过了
Please be advised that we are presently experiencing technical difficulties with the On-line Case Status Request page of our web site. We hope to have the site working normally very soon.
We welcome you to check the site again shortly. Please remain patient and wait until the Case Status Request page is working normally in order to check the current status of your application.
Thank you for your cooperation.
