Phoenix is a growing southwest business hub. Many ethnic groups are represented throughout the multitude of neighborhoods that make up the Valley of the Sun. Expatriates do not tend to settle in particular neighborhoods or suburbs based on ethnicity. On the contrary, they tend to choose residences based on proximity to work, school choices, or other criteria particular to the individual's or family's circumstances.
Local residents are welcoming and it is common for new residents to receive invitations to socialize with their neighbors. Even so, do not be afraid to take the initiative and invite your new neighbors over for cocktails or dinner.
