Chin was successful during the first and second actions.  Although the first action was not directly impactful on the first iteration of the Trump Travel Ban, Chin's action was part of the writing on the wall, and the ban was re-written.  Ching's second action (on the second Travel Ban) garnered a SCOTUS order saying Trump COULD NOT ban travel for certain groups, including those with bona fide relationships (Trump's second ban sought to exclude those in that group, as well as those with education and employment purposes, simply because of nationality.  Trump was told he couldn't do that - Chin's victory).  I think SCOTUS allowed the temporary limits of other classes of visitors because of the temporary nature of it.  But will take up the propriety of attempts at permanent bans (e.g. refugees) in October.  That's when nationality and religious discrimination will be squarely addressed.  The ruling will apply to potential bans on other naationalities.  Including yours or your ancestors.
