I am really sorry to your brother. For your concern, it depends how fast his learning curve is. Because, if he has no experience in real practice, it could be trouble. Because he needs extra efforts and training for his special case.

Accountant is essential person, he or she also needs to speak with clients and colleagues to solve accounting issue. Even in lower level accounting post, they still requires basic communication skills. Perhaps, exceptional post like Accounting Entry, Billing, maybe suitable for him. But for such routine job, it is rare in the market, because many things are integrated in ERP systems. So accountants may do the operational jobs with ERP system.

If your brother is able to use ERP or IT systems, it could be advantageous for him. He needs a special mentor to guide him in his career. I truly bless for your brother!
