Can I change from F1 student to B2 tourist ? If approved can i travel and come back with tourist visa ? Would I be receiving a copy in the mail ?

It may be possible to change from F-1 student to B-2 tourist, but such is mostly impractical at this time to a number of situations. The USCIS service centers are generally backed up on this type of adjudication and could well take over nine months and even longer to make the adjudication. If you file, you will receive a receipt, but it may take a long time before you receive an actual decision. If you decide to file and are still in the US by the time that your requested time is close to expiration, you should leave or take some other action to preserve your nonimmigrant status. Please note that a change of status is not a visa, it is only notated on a paper. If you travel outside the country, you would need to apply for a tourist visa in most cases to return as a tourist.
