Approach your Boss directly dont go through any 3rd person,many times people will spoli mood of Boss,explain the situation and request him to consider to accept and release you and also request that even you are reday to pay for your ticket to go back.

When you approach Boss definitely they will consider and may not even take any money.

Pray God before you meet your Boss that your meeting should peacefull and get released.Nothing is Impossible for God.All the best.
