Can I change my company as soon as it gets picked up in the H1b lottery and not wait till October when it gets official? Will there be a problem in h1b migration So lets say if i get it filled in premium and the result come in late april . Can I switch the company and get a h1b migration done?
Have you heard of google.com? It has all the answers you are looking for. Read this: http://www.rnlawgroup.com/news/473-selected-in-h-1b-lottery-can-i-change-employers-before-october-1
Being picked does not guarantee approval specially in this environment
Don't do it, have atleast 3 months of pay stubs before you initiate a h1b transfer
Why do you want to make your life more complicated?
