and one thing i didn't realize.. in your posting that you will be there in Nepal for like 2 mths only rahecha.. according to my adviors in skool.. if you take the semester break.. you have to leave before 1 mth and not after 1 mths.. if you leave after 1 mths.. then you will be out of status.. and it will go in your record.. and immigration will check mark on your status as out of status.. you have taken the semester break.. and you are not allowed to enter the country before a mth starting the semester you are coming back.. but depends on your classes starting in summer.. make sure and also visit your advisor about that.. calculate your class starting time.. in summer.. and make the date of arrival in US not before 1 mth of class starting in summer.. but visit your advisor.. i did all the above mentioned things while taking the semester break.. but your case is same but lil bit different as you are coming back in summer and you can also take 6 credit hrs in summer..

hope it might help lil bit taking the decision..
