H1B transferred..date issue

I just got my approval of my transferred H1B. The effective date is the reciept date for my transfer application, and expires in 3 years. I have used my old H1B for 1 year. Will this be a problem? When should I renew, in two years (old one expires) or in 3 years (new one expires)?
Any one has the same experience? Please share.
Thanks

• 6年以後沒綠卡呢? 就必須出境嗎? 另找單位也不行? -轉身份可以吧?- ♀ (0 bytes) () 06/28/2005 postreply 08:58:17
