Your friend, while on vacation in Thailand got a working visa from Qatar and she wanted to come directly from Thailand to Qatar. If this is the case, she cannot come directly to Qatar, if her working permit visa from Qatar was not yet been stamped to her passport. She need to do the necessary documentary requirement,medical examination, etc as pre-requisite from her country of origin, before her working visa will be stamped to her passport by the Qatar embassy also from her country of origin. Better let your friend seek and advice from her embassy in Thailand. If it can be arranged from there then it will save her the trouble of going back to her country of origin.
