Just heard today it is possible. At least this law was issued by Clinton that if a person have been in the US for 10 year without leaving the country for more than 6 month, he/she can apply for GC. I have couple friends who are applying for GC according to this law, but their case was kinda special since they applied to the residency while owning a business and pretty much being self-employed. They just learned that were rejected of GC but have been offered to apply for GC on the basis that they have been here for 10 years. Is this law still working? I could not find any info on this on the internet
