archibaldfrance - it's safe to say that this is one of the easiest times to find a job in New York in years. Look at Archinect's job board - there are almost 600 active job ads in New York alone. 

Many firms are unable or unwilling to sponsor a visa, if you're not a US resident, so it's advisable that you start that process on your own, if you can. 

The feedback we're receiving from firms is that it's really difficult to find good talent these days. Unemployment rates are really low for architects right now, so firms are seeing far fewer applicants fighting for available positions than in previous years. If you're good, and you put in a strong effort into your application and job search, your chances of landing a job in architecture are better than ever. 

I'm not sure we are at the point that h-1b visas are going to be sponsored when there are plenty of people already here who need jobs. Maybe the big name offices will have the budgets and need.

One of my colleagues is being sponsored but is responsible for all the legal fees. It's over $2000. Make sure you have that in your back pocket if needed.

Such a good news!! In France the market is really tough in architecture so US would be a great option for many talented french architects. I will look at the visa process to sponsor myself and will try to approach international studios. Hopefully I will be able to come soon!

In the meantime if you have recruitment agencies to recommend me please let me know! Thanks again and speak soon!

I would apply directly to firms that are advertising openings.  Going through an agency is not necessary.

I've heard firms in the US are preferring those with international experience over local undergrads. Is this true? 

Also, @sandraArchi_Pop, I'm trying to find work in Paris. Is it that bad? Even interior architecture? 

Not true at all.

Local candidates are always preferred.

LA is the frontier
