From your below message i hope you were working here in Qatar till January first but you did not mentioned under which Vis you have been worked???? If you worked here under Work permit/residents permit then you cannot come back / you will not get a work visa here. As per the labour rule there is a ban for two years to every expatriates who worked here from the date of cancelling their visa or from the date of expiry of your visa. In you case i feel you have gone back to india without cancelling your visa if you did not come back within 6months then if you want to come back to your job your company has to submit a letter in the airport, or else your visa will be cancelled automatically after your visa expiry and from that date onwards your BAN will start.
