如果是超级签证的,没有盖章默认就是2年。
Note: In general stamps issued by CBSA officers at the POE are valid for a period of:
- 6 months from the date of entry (for visitors);
- 2 years from the date of entry (for Parents/Grandparents who possess the Super Visa-PG1 TRV or Letter).
If a hand-written date has been placed under the stamp, then the period of authorized stay expires on that date.
