The president's immigration policy tends to be against the southern border and Muslim countries, this stance resonates well among his core supporters. The decision to extend the TPS is up to secretary of DHS - secretary of state - the POTUS (that order). I don't think the president will not honor the recommendation from Kirstjen - Tillerson - John Kelly - Trump (that order). There is very good new about the current DHS secretary Kirstjen Nielsen. Kirstjen has done study of Nepal following devastating 2015 earthquake. Kirstjen is former president of Sunesis Consulting based in DC and you can find the article and full report about the (Nepal's) earthquake disaster/recovery efforts which she authored here.
