Hi,

Here is my I-140 status @ NSC:
RD: 1/19/2007, ND: 1/20/2007, Category: EB2, Labor approved in PERM

Few quick question
#1: How many days it takes to get the approval?
#2: My I-94 and H1-B visa is getting expired 1st Sep, '07. And I94 extension process is in progress (through employer). Having an approval to I-140 (through PP - assuming will not more then a week or two) will have any impact (+ve or -ve) on I94 extension process?
#3: When is the best time (i.e. during which process/time) to I change the employer if I do not want to do all over again?
#4: Converting I-140 to PP will be also applicable for I-485?

Thanks in advance,
