Could someone please explain the current Covid-19 visa extension schedule? I've read the 30th January articles in two different publications and they are both confusing.

In my case, my current Covid-19 extension is up 28 February. I applied again on 27 January for an additional 60 days and am "under consideration" until 15 March. When I return on 15 March and hopefully be approved....that extension will be valid until approximately 28 April - correct? Then, as I understand it, I could then apply for the last extension on or about 28 April which would be good until 30 May.

Is that correct? Thanks for your help.
