I thought this may be interesting for others. Here is the list of things that I worried about. Lucky me, none of them happened !
1. Job role specific :- When my labor was filed,it was filed for a specific role and in the two years since then, I moved up the corporate ladder several roles, with increasing responsibilities..
2. Emp Experience letters:- I had most of them, but atleast one company\'s I did not have clearly (where I worked for 5 years before my current company). I made up for it by submitting client appreciation letters and letters from my ex-colleagues.
3. Salary Change:- I had a significant difference (>50%) between my salary at the time of filing labor to the time my 485 was being processed...
4. Address changes:- I moved between 4 states in the 2 year period since filing labor. All my applications-labor, 140 and 485 were all filed at VSC. Only the last address change I got officially changed with the INS. Rest of the paper work was coming to my lawyer, so there were no issues.
5. My company got bought over after I filed 485. But the two clauses I mentioned in a different posting - company name change and Tax ID remained the same. So, there were no issues...
6. Old H1 papers :- I think overall I had atleast 3-4 H1/L1 petitions in the 6 years H1 period and I had most of the paper work, but I certainly was missing some of the original petitions. I think I did have all the approvals...
