@SaraQahtani. Transferring to Stanford is extremely tough…even tougher than getting in as a freshman. And unless you have a very interesting story/history/unusual circumstances/military service…it’s even tougher.
Here you can peruse through this older thread: http://talk.collegeconfidential.com/stanford-university/1617549-official-stanford-transfer-2014-thread-p1.html
Hope this helps.
