Wordpress plugin advice

This seems almost easier with laravel. My 2 cents.

I would highly recommend letting experienced programmers do the coding for the wordpress or laravel due to sensitive nature of your data and compliance issues. If not coded properly system can easily get hacked and you have tons of headaches. I can refer you to few experts that can get this project done right for you for a very reasonable cost. You can discuss with them directly to get a better idea. Again my 2 cents.

I don't even understand what you're trying to say.

Perhaps you can share more about it?

Would clients provide their information on the front-end?

If yes, that's possible even with uploads etc.

Then the other one you say about then seeing more personalized information about their application processes might be achieved with Custom Post Types.

That's what I think I grabbed here, but I'd like you to explain a little more.

Great.

Please understand that there's a difference between "Filter" and "Search" these are two different types of functions.

Filter is to select from some while search is to look in to everything for one.

The front-ed form for applying for the visa can be done with a plugin like WP forms, gravity forms or Ninja Forms.

If you build this website with Elementor, you can use columns to arrange the page for workers and applicators with an advance search widget.

With the Dynamic tool in Elementor, I guess it's easy to implement custom post types from other plugins like ACF for example.

When applicator access the website, they login, they'll be redirected to their profile (a page created with a page builder) and will see details listed by the CPT plugin.

The only part I'm lost at is the approving process. Where workers have to approve the post. I think with CPT and this should be possible;

Sounds more like when a Tutor creates a course from front-end and admin approve it then it becomes available for students to access and also the tutor.

Just sharing my thoughts, I haven't done this before.
