If we issued request letter for 15th march but we can later I.e May. Than the request letter will be valid for that period or notm
Thanks for your question,
May we know type of visa which you want to apply?
Please note that, 1 month visa can stay 30 days and it will valid from the " entry date " which you filled in application form online
For example : if you put entry date for 1 month singel tourist visa is 1/3/2020 , your visa will valid from 1/3/2020 to 1/4/2020 , you can enter and exit in this period
Thanks and best regards,
