What should I fill out in my visa application for Vientiane regarding duration of stay, guarantors, travel method, and submission format?

When filling out a visa application for Vientiane, you should input '180 days' for the duration of stay. For the guarantor in Thailand, use the name and contact information of your hotel or landlord. For Laos, provide the details of your hotel or simply put 'N/A' if you have no contact. You can indicate 'By land' for your travel method. Both digital and handwritten submissions are generally accepted, but many recommend handwritten applications for a more personal touch.
