Verify the requirements
Consult the competent authorities for the destination. Citizenship, residence status and the proposed activity can affect what documentation is needed. A recruiter's message is not a substitute for checking your own eligibility, and permission to travel does not automatically mean permission to work.
Read the arrangement
Obtain understandable terms covering the contracting party, duties, pay, duration and how the relationship can end. Seek qualified advice on clauses you do not understand. Keep your original documents rather than leaving them with someone as a guarantee.
Plan independently
Confirm accommodation, travel and any necessary coverage. Keep emergency contacts and a reserve for unexpected expenses or returning home. Share your plan with someone you trust. A destination should be assessed on verifiable conditions and practical support, not only the amount mentioned in an advertisement.
