Was each visit two to three weeks, or two to three months? To an Immigration Officer, the former makes you look like a happy tourist, however the latter looks like a visa dodger.
If you get an extension, you are OK then. For me, I would never visit without an outbound ticket within 59 days. The airlines should check this during check-in, and the fact that they seldom do wonโt stop me from having proof that Iโm leaving within the conditions of the visa exemption. Good luck.
A side issue, but be careful โฆ the day you arrive is โday 1โ, so you can only stay 89 nights with an extension. Make sure your return flight adds up.
