My H-1B will expired in this March, I want to apply for next 3 year's extension.
My question are:
0. H-1B extension application is different with new H-1B application, is that right?
1. Someone told me INS will charge 1130$ for H-1B extension,
is that right? It is so expensive now.
2. Can I apply it myself or I have to hire a lawyer?
3. Some one told me it will be all right if I submit the H-1B extension just 1~2 days before my H-1B expired, is that right?
Thanks
