Even though the article mentions about the H1B Scam, it does not mention any precautions.
The quota for this year is already over and if one needs to come on H1B he has to wait till April 2008 when his application can be filed.
This year INS (USCIS) the agency for approving H1B have chosen to do the selection by lot (Kind of Lucky dip) and will choose applications. Getting H1B (Probably from here on) is now pure luck!!!
Once H1B Petition is approved then a candidate need to attend interview in US consulate for getting his Visa. He can go to only that consulate which is located close to his residential address (Meaning a person residing in Hyderabad can go to only Chennai Consulate, there are some exceptions though). The consultates have lots of information about the universities, organizations etc in their Domicile. People who are heading with Fake Certificates beware. Consulates can sieze the documents and can handover to police.
A candidate going for H1B visa need to have the original petition with him and it his right to keep it safely and he need not give it to the agent. A person to travel to US need to have approved Visa and petition papers. A person requires 2 current pay stubs to transfer his H1B visa and he is free to work for any employer (Of course In the same profession) and the employer has to pay him a minimum salary (Check immigrations sites like murthy.com or immihelp.com for more info).
