My mother and brother applied for TRV online in March 24, 2018. They weren't aware that they needed to do the biometrics right away or within 30 days of application submission. Issue is that to travel to the nearest Canada Visa application Center or Canadian embassy it will take around 30 days to get a flight, they’re traveling from Yemen. The supporting documents will be expired by then, expires in sense that my brother (who’s attached in the same application as mother) requested time off work & school will be passed by then! Mother requested 3 months’ time off work and brother 2 weeks only.
