RSM vs. St.Gallen

hey guys I'm in quite an annoying dilemma and would really appreciate some help!

I got accepted by both RSM and St.Gallen for master, pretty much the same programme, FI in RSM and MBF in St.Gallen. RSM requires confirmation in 2 weeks while St.Gallen can wait for a whole month.

As a Chinese it's quite annoying that St.Gallen requires this APS certificate (which is actually compulsory for Chinese studying in Germany but somehow I need this to study in St.Gallen). Problem is I sent in my application for APS a few months ago and apparently it's gonna take much more time than I expected. But I need to have it by Sept so I can enrol successfully.

For me I prefer a 2-year program so I'm more inclined to St.Gallen, but still RSM is a prestigious one, and so I've heard it's more common for RSM students to get a job in London. It's something I have to think about since I don't speak much German, which would be a disadvantage because St.Gallen's brand is a bit confined to German-speaking part.

I kinda want to risk it and take St.Gallen but I might lose them both if I don't get my APS on time.. and a side note I also applied for Bocconi but haven't heard from them yet. So judging from what I have now I really need some advice!

Thanks!
