Wp 3 & Wp 7

[rishi]

Here's an excerpt from some document on the BOI Website (I've omitted the entries irrelevant for my question).

<excerpt begin>

The following documents must be attached to a Work Permit application:

For non-permanent residents: A valid passport containing a Non- Immigrant visa (except for WP 3 applications)

For permanent residents: A valid passport, residence permit and alien book (except for WP 3 applications)

A recent medical certificate from a first-class licensed physician in Thailand stating that the applicant is not of unsound mind and not suffering from leprosy, acute tuberculosis, elephantiasis, narcotic addiction or habitual alcoholism (except for WP 7 applications).

<excerpt end>

I'm a bit curious about these terms. Anyone able to shed some light?

What is a WP 3 application and a WP 7 application, respectively ?

Does any of these have any relevance for someone in my situation?

I'm residing i Thailand on a non-imm O, support wife type of visa and about to form a limited co to sponsor my workpermit (managing director + expert).

Unless you have any of these diseases, I would not worry about it.
