US Immigration from Philippines

I requested an expedited interview last week. They never got back to me, but now I see the status was changed from Expired to Refused. Is that good, bad, or nothing?

What should I do now that I lost my greencard extension letter?

Here is the progression

DQ 7/10/20

Interview was originally scheduled for 2/11/21

Medical on 2/8/21flagged for sputum

Medical completed on 4/20/21.

Sent email requesting new appt 4/20/21. No reponse.

Followed @angeljolie's advice and sent email to support-philippines@ustraveldocs.com on 5/10/21 and received an automated response with case number.

After no response I sent another follow up e-mail on 5/19/21 including the case number email I received earlier.

5/27/21 I received our appointment scheduled for 6/5/21. It said expedited but I never requested an expedite. Here is what the email said:

Dear Mr./Ms. ____________:

We are writing to notify you of an expedited appointment date for your pending immigrant visa case. We have scheduled you for an expedited visa interview at the U.S. Embassy in the Philippines on 8 June 2021 at 8:30 am. No other applicants and no petitioners will be allowed entry.

Visa applicant(s) should follow all interview preparation instructions located on the Embassy s websitehttps://ph.usembassy.gov/visas/immigrant-visas/. Applicant(s) must also complete their medical exam at St. Luke s Extension Clinic and must be medically cleared for travel to the United States at the time of interview.

WHAT DO THIS MEAN?

If your qualifying immediate relative currently resides in the United States and wants to apply for lawful permanent resident status, they may apply using Form I-485 at the same time or after you file Form I-130.

MY MOTHER HAS A TOURIST VISA, CAN SHE USE THIS VISA, COME TO THE US THEN APPLY USING FORM I485? Do this mean i dont need an I-130?

Who can be a joint zponsor for k1 AOS?
