Question: I have a visitor visa for the USA for multiple visits up to June-2023. Can I apply for an extension of the visa before the expiry date? Also, advise procedure for extensions and where I can get the application form, so I can keep all details ready.
Answer: I am not aware if there is a procedure to apply for a visitor visa extension before expiration. You can send an email to the consulate to confirm. There is, however, a restriction under the consular standard operating procedures on holding concurrently valid visas of the same type.
