AFAIK after approval for the H1B, you usually have go through consular services in your home country to get the H1B stamped and to come back on it.

Change of Status H-1B petition doesn't require you to leave the US. Visa is only for entry.

F1 is the same. You can have an expired visa but maintain legal student status in the US because visa is for entry only.

		The 100K fee has to accompany the H1B petition. The enforcement happens at the port of entry. So theoretically, a) the application could be denied if it doesnt have the 100K fee. b) If it doesnt get denied then you could stay in the country without paying 100K till a change of status event? This removes any out of US travel options. Not sure how practical option b is, where you put everything on the line if a travel need arises.
