Edgardo Nuñez Cobas, 43, used to work as a cook at a five-star hotel in Cuba. He brought a certificate that shows his hospitality training with him to the United States and hopes it will help him land a job. For now, days after he arrived in America, he&amp;#39;s cooking food at a shelter where Cubans who&amp;#39;ve just crossed into the United States are staying in El Paso, Texas.
