that's a mistake my cousin made as well and i would imagine being a rather common mistake.
it was no issue none what so ever, he his passport in 2 weeks
so don't worry about it
on a different note, i see a lot of folks here recommend using Check and send service for passports, i'm not sure why people recommend it so strongly if they can't pick such mistakes up ?
am curious as to why people choose to use the post office apart from the secure delivery option ? any other benefits ?
