The entire question doesn't have any sense. I'm going to divide it. The part of "Usted si es bilingüe" means If you are bilingual. The next part: "El haber trabajado en el Valle del Rio Grande le ayudo mucho" means: "Having work at the Rio Grande Valley help you a lot" or it can be "Working at the Rio Grande Valley help you quite a lot". The last one is "Muy bien" it just mean: Great Maybe the real sentence was: "El haber trabajado en el Valle del Rio Grande le ayudo mucho". The part of "Muy bien" is a redundant and it can be a confusing for translating purposes. I'm not an expert but I did try my best. Hope this answer will help.
