I would still advise you going to nepal with a stamp. I'd recommend Canada/Mexico to get a stamp. Since you are sure you're H1 will get approved, you rather not take a chance. H1-B entitles you to seek dual status i.e. H1B and PR but under F-1, you are only entitlled for one. Under the Law, you should have no intention to reside in the U.S. after the completion of your education. So once you have your H1, you can argue that it is dual intent but under OPT, that is considred illegitimate, if not illegal. It's a tough decision. The choice is yours. -LoGiN
