Thx dear. Btw I saw your posts on others which state that once you apply & pay for 820, then you're eligible for Medicare. Please confirm...
Read it for yourself. It's stated on the Medicare website that applicants for the 820/801 and 309/100 are eligible to apply for Medicare.
FYI, it's not an 820 application but a joint 820/801 application. The 801 part of that is an application for permanent residency (although you're not eligible until two years after the application unless the long term relationship criteria applies to you), and that application for permanent residency is what makes one Medicare eligible.
