A proposal for facilitating of Iranian students travel to home

The Honorable .........
I am an Iranian student studying at SMU towards PhD degree in Mechanical Engineering. As you may know there are a lot of Iranian students in Texas and US who are studying in graduate studies in different universities and academic institutes and I want to share one big problem in this community with you and ask for your help and consultation.
Iranian students are among a few nations who hold single entry visa(F1) while they are studying here which means if they want to visit their families back at home, they should apply for visa again and go through very time-consuming and difficult process. Since there is no US embassy in Iran, they should schedule a flight to third country, get an appointment for interview, wait for FBI check , pick up the visa to be eligible to come back to school again. Also, add the stress of visa rejection to these problems which make this trip very unpleasant for most of my friends such that a lot of them prefer not to visit their families, while their international friends go to their homes easily and this add some emotional pressure during their long period of studies.
I want to ask you if there is any way to facilitate this process and I have two proposals for that:
1- Iranian students, holding F1 visa, can go to a consulate office in Washington or somewhere in US to perform visa process if they want to visit Iran.
2- The embassy of Switzerland in Tehran is in charge of US interests in Iran. it would be great if this embassy do the visa process for Iranians on behalf of US government and send their documents to Washington for FBI check, in this way, students don't need to go to a third country and it facilitates their trips in a great deal.
I would appreciate if you consider these proposals and let me know if each of them is feasible.
I hope I see one day that the citizens of both nations visit each other's country freely and easily!
Thank you very much!
