My son is on an Ed visa- and my trailing visa- is a Non-Imm O- both 90 days. When arriving, I showed documents to immigration, and after realized our stamps seem to reflect- just a 45 day tourist entry. Isn't this supposted to reflect 90 days on the entry stamp? And now, do I need to go to immigration to sort out? If there is anyone out there that knows of what to do, I would be appreciative of any info.! I have booked ourselves an immigration appt. so that they can check our status.
