In a statement, the embassy said applicants across India may have to wait 30 days or more for a visa interview appointment to become available and that it expects this wait time to continue for at least the next few months.
"The US embassy and our four consulates are constantly working to improve service and meet demand, but applicants should be aware that the summer is a peak travel season and there will be delays in getting visa appointments. Travelers should apply early to avoid potential delays," the embassy said.
It also asked people to be aware of scams and fraud.
"The only way to get a US visa is through official channels. Someone can either apply and have an interview at a US Embassy or Consulate, or if they have had a visa before and meet certain criteria, they may qualify to have their visa renewed.
"Anyone claiming they can guarantee a visa in exchange for a fee is attempting to defraud you. Applicants should be smart and apply the right way," it said.
The embassy said consular sections in the US mission are currently only able to expedite visa appointments for cases involving genuine emergencies.
