Wire transfers to the US relatively seamless. Each TT will cost your around USD 30.00 (100 Dits). The banks will set up a standing transfer with no problem at all. Trap for young players if you ever do a TT - there's frequently another charge at the other end - and the bank there, (and sometimes the UAE bank as well, unless you take great care in noting that charges should be taken from your account and not the remittance) take their cut from the amount you send, so the person you're sending the money to gets only the amount you sent less the bank charges, which can be embarrassing if it's a mortgage or alimony payment you're making.
The major question you should be considering is: will you have enough readies each month to make a standing transfer to the US? Possible if you're coming as a DEC, or, if as an FO, you don't have a family to support here, but most FOs would say they don't have a lot left over after covering day to day life.
The average married with two kids EK FO's lament is something along these lines:
"Why is there so much month left at the end of the money?"
