is confusing.

1) You say you are ready to go back home and change visa to husband sponsorship. Do you already have a work visa here? or are you here on a visit visa ???

2) he is a safety coordinator in what company ??? if it is qatar gas, qatar petroleum etc, the HR there can arrange for the family visa in spite of the profession problems.

3) if you are here on a visit visa and want to come back on husband sponsorship, then he / his company has to submit all relevant documents to the government and get his profession changed on the visa (this is on the sole desecration of the employer as he might not have a visa which suits his job)
