Though there are suggestions a particular Job site offering job for teachers to an applicant needs in applying for the opportunity, the physical address of the agency might not be reachable to all the applicant. The same with the agency website offering services to process the travel documents needed. If this will the your situation, I would like to suggest you look for an agency near your place to process all your travel documents.
Job sites for teachers hosted from other countries are not and in no way they could be able to access those data to be presented in the Department of Foreign Affairs in your place. The department is in your place or country; thus, you are the only person who has the capacity to access these processes.
In addition, you can also easily determine the authenticity of that particular agency you want your papers to be processed. Just give yourself time to check the license of the agency if it is really authentic and registered in the authorize government agency. Travel agencies or recruiting agency has posted legal document like their license on strategic location in their offices. This will be your basis and data to present to authorities to check the authenticity of the recruitment agency.
There are recruitment agencies which may be connected to that job site who posted a job for teachers. If this will be the case, then applying for that job for teachers or any other online will be easy. Of course, there’s no such thing as better as the the one you are personally speaking with the processor. Chatting online or sending documents online is risky, even if you will have the chance to speak via webcam the person in-charge on the website offering that job for teachers or any other job opportunity via the internet.
Check out those recruitment agencies near your place. For sure, there’s that job for teachers or any other job opportunity you are looking for.
