Q1: How can we become a Buddhist?
A1: Well, to become a Buddhist, there are two things that a Buddhist must do: 1. Taking refuge in the Buddha, who is a physician and who is skillful in the knowledge on the cause of the disease and how to cure it, in the Dhamma that is a very scientific prescription by taught the Buddha and in the Sangha that is nursing staff to help suffering humanity.
2: Seriously taking the five precepts: not to kill any sentient beings, not to take what is not given, not to take sexual misconduct, not to tell lie, not to take intoxicating drinks and drugs as much as you can.
This is the way how to become a Buddhist.
Q2: Can we do here or is it possible to do it in other countries like in Europe to become a Buddhist?
A2: To become a Buddhist, you can do everywhere all over the world. You just need a Buddhist monk Senior master at the presence of whom you become a Buddhist.
Q3: What do we have to do particularly when we are Buddhist?
A3: When you are a Buddhist, you have to do four things everyday. 1. You have to take a refuge in the Buddha, in the Dhamma and in the Sangha. 2. You have to observe the five precepts everyday by reciting in Pāli with their meanings. 3. You have to do Mindfulness-Based Vipassanā meditation, at least for half an hour everyday. I always recommend that you should do these three in early morning before you go to work.
4. You should do Dāna, generosity particularly to the monastic Sangha because they are honestly trying to preserve the Dhamma by seriously learning and practicing every moment to keep the Dhamma alive in their hearts so that they can help Suffering humanity. However, you can do Dāna, generosity to the poor, to homeless, to the sick and to the orphanages and finally even to your parents everyday the best you can.
These are what you have to do when you are Buddhist. To know more, you should learn with a well-versed and learned monk by sometimes staying in a certain monastery as taking a 7 retreat. I hope you get it.
