So I opted for a single entry "o" visa. Marriage visa. I usually got the multiple entry for the past 10 years. We fly home on the 89th day this year. My question is mostly for next year. Can I get the single entry and go to immigration and pay for another 30 days? The 1 year "o" visa is $200 where the single entry fee is $80. It may save a bit of cash but will definitely save the hassle of traveling to the border.
TLDR : Answer Summary
The user is inquiring whether they can extend their single entry 'O' visa by paying for an additional 30 days stay after their initial 89 days, as they used to opt for a multiple entry visa in the past.
