@Robert ******

as promised here's the "stamp" I was referring to 😁

Thanks for the replies everyone!!

Thanks Barry

Thanks Luke

Thanks for your reply, I did not cross the border every 90 days but went to immigration every 90 days to report. I do have the big stamp in my passport that says permitted to stay until 20 April 2020... I went yesterday for my 90 day report and there is now an additional stamp which says this is not an extension of stay and I must notify my address again on 6 July 2020, with a handwritten note above it that says Visa BXQ (it looks like) 20 April 2020
