Thanks @cleo007 , but reschedule option is not appearing i still have more than a month for the appointment date.
Not sure how long it will take to have new RTD, do you think i should take a chance on the existing RTD, its 5 months and few days left (less than 6 months)
My brother rtd was expired and he returned from the door. 5 months not qualify visa rule not only us most countries consulate recommend more than 6 months. For more contact visa support team by email
