An "immigrant" refers to a person who has moved or come to a different country to settle permanently. In the given sentence, Raman is described as finding it difficult to adjust after coming to a different country from his own country with the intention of settling. "Immigrant" accurately captures the situation of someone relocating to a new country for permanent residence.

"Pilgrim" typically refers to a person who travels to a religious or sacred place for spiritual purposes. It does not represent someone who moves to a different country for settling.

"Globetrotter" refers to a person who frequently travels or journeys to different places around the world. While Raman has come to a different country, the term "globetrotter" implies a continuous pattern of traveling rather than settling in one specific location.

"Gypsy" historically refers to a member of a particular ethnic group characterized by a nomadic lifestyle. However, it is considered an outdated and potentially offensive term. Additionally, it doesn't specifically relate to someone who has come to a different country for settling.

Therefore, "Immigrant" is the most appropriate one-word substitute for the underlined group of words as it represents someone who has moved to a different country for the purpose of settling.
