Dear forum users,
3 weeks ago I've got the USA R J1 Visa in my passport (for 4 month) . Due to some reasons i had to cancel it. Now those reasons are not more "validate" so my concern is: "Can the embassy withdraw the CANCELED visa and make it valid again" or "I have to apply for another new visa in order to be able to travel to US".
Thank you in advance for anybody that could give me a hand.
