How can I add a newborn to an existing DTV visa while in the USA?

When processing a visa application for a newborn as a dependent of a DTV visa holder, it's important to note that a newborn cannot be added to an existing DTV visa. Instead, you must apply for a separate DTV visa for the newborn. The application process is the same as for the parent, using the appropriate online resources. Additionally, a newborn typically doesn't require a visa until they are 15 years old, and special considerations may apply for overstays in certain circumstances.
