The next significant wave of immigrants came in the mid-1970s through the 1990s with refugees and asylum seekers from all around Europe, Asia, and Africa. The number of asylum seekers increased significantly in this decade, such that it surpassed the allotted quotas for refugee populations and the Norwegian government had little opportunity to plan for and anticipate these waves of immigrants. Following the Vietnam War, a significant number of Vietnamese asylum seekers found their way to Norway. Following the coup d'état in Chile in 1973 and subsequent Pinochet regime, a number of Chilean refugees made their way to Norway. Both of these demographics reported feeling loneliness and isolation from the greater Norwegian populace, largely due to linguistic differences. By 1987, Norway housed asylum seekers from 60 different countries, with the largest numbers coming from Iran, Chile, Sri Lanka, and Yugoslavia. As Norway joined the Schengen area in the 1990s, immigration policy continued to become increasingly restrictive. The topic of illegal immigration became hotly debated across Europe, yet many refugees managed to stay in Norway even without the necessary documentation on humanitarian grounds.
