Being an international student of two foreign countries, with two foreign languages and cultures put me into shoes of students I am focusing on in this dissertation. Along this way, difficult times have taken turns with times of joy and gratitude. There were moments when I wished I had never done the decision to live and study abroad and, maybe, the same number of moments when I felt as the luckiest girl in the world to get this chance. And here I am, at the end of this journey, crying tears of joy and gratitude, luckiest girl in the world, knowing that without people I have had by my side, I would not probably manage and most importantly, I would not be the same person as I am today and I am proud of.There are so many wonderful people I would like to thank to. To start with, I would like to express my gratefulness to my supervisors, my precious guides in the academic environment, to Prof Francesca Pedone and Prof Raquel Casado Muñoz who taught me a lot, supported me and became part of my professional and private life. I will always remember their kindness and will do my best to feel my future students as safe and welcomed as I experienced with them.To find a real friend for a lifetime is hard, and I was lucky to get few on my PhD road.My charming and cheerful friend Gamzettinka who experienced the same troubles with foreign languages, the same moments of up-and-downs, and who used to draw me away from my laptop to get some fresh air and socialize a bit, deserves a big "thank you" because if there was not her, …., no, I will not even think about it! I also cannot forget my lovely Italian friends and colleagues Cate, Carlita and Dani, who countlessly helped me with language and made me feel more comfortable in a foreign country. Thanks to all of them, Italy was my second home. This dissertation could not be done without precious advices and help of experts who helped with the creation of a completely new questionnaire. I would like to thank to Prof Fernando Lezcano Barbero who dedicated a lot of his time and used his personal connections to help me with my research in Spain. I am also very grateful to all participants of the research and appreciate their time and willingness to participate.Last but not least, special "thank you" in special paragraph belongs to my beloved super supportive and loving husband, Adam, for being always here with and for me. I could not wish for more.Thank you! Grazie! Gracias! Děkuji! CONTENT CONTENT .
