Choosing the right bank account

Look, first of all, forget about high yielding investment options.  Every bank offers investment options to its customers but I would not classify them as good or even adequate investments, let alone high yield.  This is the case for all retail banks. For better options, you have to be a high net worth individual and be savvy (Simply: Have $100K or more to invest, net worth of at least $1 mn  and know about how financial markets work - if you do not fall into this category, don't expect any return on your investments beyond low single digits, at least, on the ones being offered by banks in this part of the world).  Essentially move away from retail banking and into the world of private / offshore banking.

Other than that, for international reach, it's good to go for a bank like HSBC etc., so if you move countries, you can still link your accounts.   Saudi to Bahrain transfer is free between SABB and HSBC by the way and gets you good FX rates.   You are not likely to get a credit card without depositing funds against that.
