Premium processing is for the petition, not the visa.
Assuming your L-1 petition is accepted you next fill in your DS-160, you also fill DS-160 forms for each family member. You then schedule a consular interview for all family members, giving the DS-160 for references for all the family.
The two have nothing to do with each other. L1 is a nonimmigrant visa. It has nothing to do with the process of getting permanent residency.
To become a permanent resident through an employment-based category, the employer must petition you (there are certain subcategories that can self-petition). You working for an employer on L1, H1b, or any other status ...
Generally, L1 is a visa to transfer people with specific knowledge/expertise between the branches. So if you're transferring into a new position, and your expertise for that position is of a "user", expect troubles explaining why you're needed in the US both to the USCIS (may be easier given lawyers will write tons of stuff which may have nothing to do with ...
I will getting just one additional year (subject to clearing the lottery)
That is correct. The time you spend in the US on L1 is used to determine H1B validity, so you will only get 1 yr more unless (see below)
Cost of H1 has increased significantly so I am not sure if this is worth for one extra year.
Really depends on what you want. If you are willing to ...
I don't think people who are already permanent residents can get a nonimmigrant visa or otherwise change into nonimmigrant status without first abandoning permanent residency (by filing I-407 at a US consulate abroad, which requires you to declare you have no intention of residing in the us). This is because all nonimmigrant statuses are intended to be ...
L-1 is not subject to the presumption of "immigrant intent". That means it's perfectly fine to have preconceived intent to immigrate on this trip when you get your L-1 visa or when you enter on L-1. Even if you intend to file Adjustment of Status the day after entering, that would be fine to disclose.
So you don't have to worry about any questions about ...
Given that H1-B visas require that you have an employer-employee relationship (which means that 1099s are not acceptable) and any employment must be complaint to the H1-B regulations and approved in the USCIS forms, no you cannot.
For an L1 visa, the answer is also no because you can only work for the petitioning employer.
Is there a simple way to withdraw the TN i-129 petition?
Yes. The prospective employer who submitted the petition can write a letter to USCIS informing them that they are withdrawing the petition.
If I go out of the country and come back, can I get in with my L1B (L1B expiry is next year)?
As long as you still work for your L-1B employer and continue ...
can i travel to mexico by air and come back again and will it give me a new I-94 ?
can i go anytime before current I94 expires ?
What are the various documents required ?
Your passport, your visa, and your valid I-129 petition.
what is the best time to go there ?
"Best" in what respect? For this purpose it does not matter when you go, ...
An I-130 is a petition for an alien relative. That's a family-based visa and inappropriate for someone you plan to hire.
An I-140 is a petition for an alien worker who has extraordinary ability or has skills that are not available in the USA. It is filed in connection with the EB-1, -2, and -3 visas. I believe, based on a colleague's experience, that it ...
It doesn't look like it's possible:
In accordance with section 24(1) of the Employment Permits Act 2006 as
amended should a non-EEA national, for whatever reason, cease to be
employed by the employer during the period of the Critical Skills or
Green Card Employment Permit’s validity, the permit and the employer’s
certified copy must be returned ...
I asked an immigration lawyer and they said the two are mutually exclusive - a permanent resident may not request a visa (even a dual-purpose one like an L-1), and an L-1 holder getting a green card is no longer considered an L-1 holder.
L1A is for international execs, L1B is for special knowledge. For L1A you'll need to show that you manage work of other people and budgets across borders. Generally, L1A requires prior management position before transfer (at least all the L1A's I've met had to show that). If you're individual contributor or a junior manager (i.e.: team-lead level), even as a ...

The filing fee for Form I-765 is $410. You must also pay an $85 biometric services fee, for a total of $495, if you are:
