<p>Is it possible to switch into SFS if you are a junior in MSB?</p>
<p>It'd be pretty impossible. There's too many requirements unique to the SFS, not to mention language proficiency/study abroad. </p>
<p>It's hard enough to switch in as a sophomore.</p>
<p>You may consider applying for the MSFS which allows you to graduate with a BSBA and MSFS with just one extra year of studying. A classmate of mine did it and ended up at Goldman Sachs.</p>
