Thank you very much for your answer. Last time I received that paper was in my last extension of my former ED visa. Then, I went to do the report to CW but, due to covid-19, I was told I dont have to do it and they sent me back home; my visa expired that same week and I passed to be under amnesty. On july I updated my TM30 and took the chance to try with the 90 days report, and I was told I cannot do it because i was under amnesty and didn't have valid visa. Then, I got 60 days extension based on visiting family, they didn't give me that paper you show (I imagine because I was allowed to be only 60 days since that moment). Finally, this week I was granted with an extension of one year, based on marriage with thai woman (sorry for using not accurate terms) and, due to I didn't receive that paper, I asked what can I do at immigration and then here.
