Thanks a lot!

So this certificate will be valid for life time? What kind of visa are you talking about, any kind, i mean say for example, H1, B1, H4. How many times can I use it?

If I eventually want to continue my life in US and is seeking for GC again, will this history help or will this be harmful to the new GC process.
