wrong! and confusing?

1> "我們在網上看到1st preferrence 排到2000，3rd preferrence排到1997，"

2> "其中一個律師說即使是3rd preferrence, 我未婚夫的排期也到了，應該對他沒有太大影響". This is correct b/c the I-130 was filed in 1997."

If he is at 1st preferrence, he should be approved already, because 1st preferrence 排到2000. ???

Please do not marry him just because of GC.
