Visa Advisory Agent

Author: Venkata Sudhakar

Indian passport holders planning international travel often struggle to find accurate, up-to-date visa information for different countries. A visa advisory agent can instantly provide visa type, required documents, processing time, fees, and practical tips - saving hours of research across multiple embassy websites.

In this tutorial, we build a visa advisory agent for Indian travellers. The agent looks up visa requirements by destination country, checks the purpose of travel, and generates a personalised checklist of documents and steps to follow.

The below example shows the agent advising on visa requirements for a business trip to the USA and a holiday in Thailand.

Connect this agent to a live visa requirement API or web scraper for real-time accuracy. Add a document checklist generator that creates a PDF checklist the user can print. For a complete travel assistant, combine with the travel itinerary agent from earlier to cover both visa and planning in one workflow.
