Can an American Citizen visiting India (doesn't have the OCI card yet), leave India for a week long vacay and then come back into India without issues? (kids are American citizens but I have not yet applied for OCI due to n number of reasons, and we have booked our tickets to Sri Lanka for this June!!!)- am worried sick as we have made plans with our friends and tickets were not cheap! They do have multiple entry visas. Thanks in advance!
