If you are starting a visa application, the best place to start is the US Embassy in your country. Here is a complete list of US embassies (and their official sites) all over the world. (we need to create this map or make this an interactive list somehow). Other resources include: the U.S. Visa Service website, the official U.S. Citizenship and Immigration Services site, and the U.S. Department of State. If there is anything else you need to know, don't hesitate to contact us at ask@oliver.ai
