FHA loan requirements question

[Kory Bizal]

Hey there, I've searched into this a bit, but I just want to make sure I'm understanding it correctly. 

I have been working abroad for 4 years and I'm about to come back to the US. Am I correct in thinking that I would need to get a job as soon as possible within the same field, and then hold that job for 6 months before applying for an FHA loan; more specifically a 204k?
