1.Make sure all materials are complete, authentic, and valid. If the documents are incomplete or false, the visa may be denied.
2.Find out in advance about the type of visa and the requirements for your application. Different types of visas have different application requirements and processes, which need to be understood in advance.
3.Have travel plans and proof of accommodation ready. The travel plan needs to detail your itinerary and purpose, and the proof of accommodation needs to prove your accommodation arrangements for the duration of your trip.
