It might help. If you submitted your documents in Singapore then it would probably help if you could find the fax number of the embassy there and request your employer to write to the embassy and fax the letter to them. I hope that your LMO is still valid up to this time. Your employer has to mention your file number and of course your name and the reason why he/she needs to employ you. No harm done in trying what worked with your new found friends. Be blessed.
Thanks you so much job_seeker..i think you are right. I will try to ask my employer about this.
As you've said, there is no harm in trying.
God bless you.
