Fredrick W VoigtmannImmigration Attorney
You could search the internet for Vietnamese speaking attorneys with EB-5 experience. Be careful, though. You should insist that the attorney is an experienced EB-5 attorney. If not, then perhaps they might co-counsel with an experienced EB-5 attorney. That way, you get the benefit of their language ability and communication, but you also get the benefit of being represented by competent counsel, as is your right.
