How difficult is it to get a US visa through an employer in the States?
Answer:
depends on the job, the employer's viability as a going concern, your qualifications & credentials, and what the job really requires. H1B is a common work visa, but it is for specialty occupations. Specialty occupations is a term of art that means highly skilled (internationally recognized) fashion models OR jobs that require the equivalent of a bachelor's degree (or higher) in a field related to the job. L1 is another common work visa, but you have to work abroad for at least a year for a foreign affiliate of a US company before transferring to the US affiliate.
Note that these are temporary work visas. You can also get an immigrant visa (green card/permanent residence) on the basis of employment, but the rules are much stricter. Usually, the employer has to show that there is no US worker (a citizen or GC holder) available to do the job. This step is called "Foreign Labor Certification" and it is done through the Dept of Labor. Once DOL certifies the case, it can proceed to the filing of an Immigrant Petition for Alien Worker (I-140) and then on to adjustment of status (AOS) or consular processing of the immigrant visa.
This is general info, you will need to consult an immigration attorney. Cost for H1 or L1 preparation can run from $1500 - $5000, GC prep cost $5000 - $10000.
there are other ways to get a GC like marrying a citizen, national interest waiver, self-sponsoring for extraordinary or exceptional aliens (the "nobel prize" and "best & brightest" categories).
Pretty difficult. However, it also depends on what you do. For example, if you're a scientist you should try to find US companies that work on similar research as you, contact them, and prove to them that you are worth all the hassle of a US work visa (e.g. you have lots of interesting publications, discoveries...etc.) It's easier to find jobs in US from abroad when you are a scientist, an engineer, or a programmer, however, you probably won't find anything if you're a hair dresser or a cook (unless you're a really famous hair dresser or cook).
That being said you can also find a US company where you live and apply for a job post there. If you get accepted and if they gain confidence in you eventually they might send you to US to work for their headquarters for a while or may be even forever (of course all depending on the situation).
