In this paper, we study quasim\"obius invariance of uniform domains in Banachspaces. We first investigate implications of certain geometric properties ofdomains in Banach spaces, such as the (diameter) uniformity, the$\delta$-uniformity and the min-max property. Then we show that all of theseconditions are equivalent if the domain is $\psi$-natural. As applications, weanswer partially to an open question proposed by V\"ais\"al\"a, and provide anew method to prove a recent result of M. Huang, Y. Li, M. Vuorinen, and X.Wang in [On quasim\"obius maps in real Banach spaces, Israel J. Math. 198(2013), 467-486], which also gives an answer to another question raised byV\"ais\"al\"a.
