How long will the approval letter stay with me before it expires?

Dear Sir

Thanks for yoru query.

We are pleased to inform that expired date is depend on yoru visa's type: 1 month, 3 months or 6 months and the visa is valid from your date of arrival which you put on Visa Application form, not valid from date of booking. Thus, you should not worry about that, you can apply visa right now though you will enter next 3 or 4 months.

Thanks,

Evisa Team
