US Immigration from Jamaica

Good evening, everyone! I hope this message finds you well. My mother is currently in Jamaica, and I am seeking advice on how to bring her to the United States for surgery. I am a citizen of the United States, while my mother is a Jamaican national. In March 2025, she was diagnosed with meningioma, which are brain tumors. Although the doctors had planned to perform surgery, it was ultimately cancelled. Recently, the hurricane has impacted the hospital in Montego Bay, Jamaica, and they are now planning to discharge her despite the presence of the tumor in her brain. As a result of her condition, she is unable to walk, talk, or eat, and is being nourished through a feeding tube. I would greatly appreciate any information regarding options available to facilitate her travel to the U.S. for this surgery, as she does not possess a visiting visa. The intention is for her to undergo the surgery and then return home afterward.

My mom recently had her Visa interview after she arrived here in the US. How can she get her husband here through the follow to join?

What time of month or day of the week does Johannesburg embassy usually issue ILs for CR1/IR1 visas?

How to fill out I 130 form for parents?

I recently created an AVITS account for my mother's IR-5 visa interview. After selecting the delivery method, I see a 'Pending Appointment Request' status. When I try to book an appointment, the system shows 'Currently, there are no appointments available for the selected location.'

Could someone clarify: Should I keep checking the system for available appointments, or will NVC schedule the appointment and notify me
