<p>So I emailed two professors a couple of days before Christmas asking if they could write a letter of recommendation for me for a summer internship I really want. One professor responded the next day saying yes. The other one has yet to respond. How long should I wait before sending him a follow-up email? It's winter break right now and he could be on vacation. I don't want to bother him, but the deadline for the application is Feb. 1. Advice?</p>
<p>You waited until the holiday break so you shouldn’t expect a reply so soon. It’s the holidays, people travel, don’t check their emails, etc. </p>
<p>Give it until the start of the semester and talk the them in person. Whenever you want a letter, always give advance notice especially during the holiday season.</p>
<p>Ok, thanks. I’m just afraid that he saw the email but was too busy to respond and ended up forgetting about it</p>
