I am also having the same problm guys.. I done b.tech and then MBA. I m hving 2 yr work experience in networking. I applied for graduate certificate in networking snd got rejected. I m very much confused to wt to do next as I dnt want to go for masters or phd rather I want to do some pg diploma of 1 yr. Bt I came to know that if I go fr pg diploma there are again chances to refuse thevisa. Guys I m very much confused like what to opt.
