I just received my Non-Imm Type OA Visa. There is no "enter by" date. Am I still able to take a border run toward the end of my first year to have it stamped one year later? The ONLY dates on my Visa are Valid from (the date they processed the Visa) and Valid Until (1 year from the date issued) and my birthdate. If someone can clarify how this works, I would appreciate it.
