got less than 6 months validity then that is true ... he won't be able to go back. I don't know why it would take 15 days or a month to renew a passport ... What is about the new passport? He can't get that one?

He got no option but to delay his trip if the passport is not yet renewed, do you think that there is another option?

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. (Gautama Buddha)
