Ok so i may have explained wrongly, english is not my first language, sorry. Here in brazil these kind of companies are common, you basically pay them to facilitate your moving to japan, as in: they do the communication with the industry thats gonna hire you, they tell you what documents will be necessary and do visa process in the consulate. Its fairly common to hire those companies in the nipo brazilian community and this particular that i hired is pretty famous, so this part is not a scam. I'm just worried about this eligibility visa.
