You are not allowed to sponsor a brother in law for an immigrant visa. Instead, your wife, (once she is a USC) is able to sponsor him for a green card. That process will take several years however. In terms of your question, it sounds like he has been denied for a visitor's visa several times and probably has another interview for that visa? They want to see that he will return to the US as promised- all consulates are scared that the person will enter the US and not leave, in particular from a poorer country like ES. So he needs to demonstrate strong home ties-ownership of home, car, business, strong financial statements, family, round trip ticket, etc. You can provide the I-1345 form and your financial information, where you promise to support his basic needs in the US, but again, often times, the denial is given because the US consulate is unconvinced of the person's intent to return.
