As an HR expert, I can provide you with some information regarding this matter. Generally, the salary offered for a job vacancy in a government agency is based on the salary scale determined by the agency itself. This salary scale is usually applicable to both citizens and non-citizens. So, as a citizen, you should not worry about your salary being deducted just because you found the job vacancy through an online search engine like Google. Your citizenship should not affect the salary offered to you. However, it is always recommended to discuss the details of the salary and benefits during the interview or negotiation process to ensure clarity and avoid any misunderstandings. The agency will take into account factors such as your qualifications, skills, experience, and the nature of the job itself when determining your salary. I hope this information clarifies your concern. Should you have any further questions, please feel free to ask.
