I'm referring to visa exempt, if you extend it for 30 days can you do a border run after the 90 days, it seems you can re enter as many time as you like as long as you stay no longer than 60 days so does that mean after staying 90 days with an extension you still can re enter up to 6 months, so you could re enter 3 times in one year, total 6 months, or once with an extension then do another run giving you 2 more months total 5 months then another after that giving you 7 months total , is this right??? appreciate reply thanks Dr Jack
