Before going to the United States, you must participate in the required Get Ready Workshop. It worked in the same way as the Matching Workshop, sitting in front of your computer, listening to someone who tells a little about what to expect when traveling to the United States. For example, they are talking about the culture and that it will be different from your own and things will not be as used to.
You also get to know a lot about the so-called honeymoon phase, starting from getting to his host family (sometimes even before) and varying from person to person. In some, it lasts only for one week and for others it lasts for three months. And it's the stage when you feel that nothing in life could be better, you are on the adventure of your life and standing on top of the mountain.
Before participating in the Get Ready Workshop, you should read the Get Ready Guide that you get send to you. And it's important that you study it carefully as they will ask questions about things you read there.
