If you know that your company is willing to file H1B, then why wait? and make things complicated? Let them know in advance and you know things might not turn out to be on your side when they find out later on and it might be too late for you if they decided otherwise. Also, EB2 and EB3 terms doesn't apply to H1B filings ( although I know what you mean, and yours is other way around). EB2 and EB3 are terms used in green card process. Bachelors Degree is 65K and Masters and above degree (advance degree) are 20K. Also, Out of that 65K, I believe 10K or 5K are already gone to Philippines and Hong Kong Nationals. I don't see any indication that quota will be increased for this year filings. Looking at this year filings (2013), June might be late for you since I think within a week all quotas applications were full. Things were different prior two years 2011 and 2012. IN 2011, They were accepting application until late October and November. AT this point there is nothing you need from your employer besides job offer letter. My best suggestions to you - Let your employer know that what happened last year with H1B filings. Convinced them to file your H1b in the first week of April ( Don't wait until June; I doubt that there will be any left). If you are Masters quota, then you might have more than a week, But I doubt that Bachelors will have any left after 1st week. If you have a OPT or if you can extend OPT until next year April 2015, then your best bet would be to work on OPT.
