H4 COS, application for TN COS pending, I-485 application as a dependent

[ranga_cit]

Hi,

 I am working on applying for concurrent processing of I-140/I-485 along with my wife (she is applying as my dependent). She is Canadian by birth. I am on H1B and PD is current through Canadian cross-charging

She entered in F2 status (with stamping at port of entry), changed to H4 COS and she has got a job now, for which TN COS is being prepared (premium processing).

We plan to delay filing I-140/I-485 till TN COS is approved.  Two questions:

1) Is it OK for her to be in TN category, when our I-485 is filed? It is a non-immigrant category, that's why asking?

2) In Nebraska processing center, how long does it take to get EAD after I-140 is approved (for a pending I-485)?

TN status does not allow for Immigrant intent. Please help yourself and talk to a Lawyer before you make major errors of judgement.
