Waiting times and hurdles between inclusion in ESCI and getting an impact factor?
No hard and fast rules here but the answer is about a few years.
The publisher is the only one who can make the application (see this page, &quot;Submitting your journal for evaluation&quot;). Of course they are heavily incentivized to do so, but they will only do so if there's a reasonable chance of success, since failure means they can't submit for evaluation again for at least two years. So that's the approximate time frame: about a few years, depending on whether the publisher judges they have a chance of success and when they apply.
