This page lists migration information web resources that do not engage in explicit advocacy and are generally considered neutral or objective sources. For sources with an explicit pro-immigration agenda, see pro-immigration web resources. For sources with an explicit anti-immigration agenda, see anti-immigration web resources. See also immigration law web resources and consumer-oriented visa and migration help resources.

Note that just because a source claims to be objective or neutral does not mean that its research is necessarily higher quality or that it does not have an agenda. Conversely, just because a source has an explicit, upfront agenda does not make its research necessarily unreliable or low quality.
