Is Multiple H1B Allowed Legally Not Possible

H1B the most popular non-immigrant visa that offers employment job opportunity for a minimum of 6 years with further extension possibility is a dream come true of many asians particularly people of India and china have this as lifetime ambition. So, is it possible to have multiple H1B filed for you?
It is a tricky question. There are two possible scenarios :
1) Applying for a fresh H1B visa - This also includes change of status from F1 to H1B, H4 to H1B etc. So in this case what if I file multiple H1B?
What is multiple H1B visa?
1.1) H1B visa is sponsored by an america employer to his employee
1.2) If more than one employer say two companies company A, company B file new H1B visa for a person this case is called as multiple H1B visa. Until 2006 this is legally permissible. From 2007 onwards US government has legally banned this. So, for initial filing for new H1B visa go with a single employer. Multiple H1B filing is not allowed
2) H1B Transfer - This is in contrast to new H1B filing. If you want to switch jobs from company A to say company B, company C you can clear both interviews and ask both employers to apply for H1B transfer. You can choose to join company B or company C later. You need not have to join them. This process usually called as H1B visa transfer in which case filing by more than one employer at same time is permitted.
