[General] General: I may won't be able to know you at the airport

[sb70012]

Hi,
Suppose that I am chatting to a girl in Paltalk messenger. She is in different country. I decide to go to her country and see her.

"Jennifer, please send me your picture before I leave my country because I may won't be able to know you at the airport"

1. I may won't be able to know you at the airport.
2. I may won't be able to recognize you at the airport.
3. I may couldn't recognize your face at the airport.
4. I may couldn't know your appearance at the airport.
5. I may couldn't know you at the airport.
6. I may couldn't recognize you at the airport.
7. ............
(I don't know how is natural to you native English speakers)
How would you say the bold written part? :?:

Thank you.

7. I may not recognise you at the airport.

8. ...so that I can recognise you at the airport.

8. ...so that I can recognise you at the airport.

Thank you.
If I use number 8 then I must omit "because" right?

I may won't .....
I may can't ......
I may couldn't .....

Are these ungrammatical?

 

[engee30]

Yes, they are. A modal verb doesn't allow using another modal in the same verb phrase.

 

[Raymott]

I may won't .....
I may can't ......
I may couldn't .....

Are these ungrammatical?

Yes, all of your original sentences are wrong.
Instead of "1. I may won't be able to ..." you need "I may not be able to ..."
I don't know what you mean by "may couldn't". "I may not have been able to ...?"
